What is one of the 2 sides of the right triangle that form the right angle?
In a right angled triangle, there are three sides. The longest of these is referred to as the hypotenuse. This longest side is always the side opposite the right angle. The other two sides are most often referred to as the "opposite" and "adjacent" depending on which other angle you are looking at. If you look at an angle other than the right angle, it will touch two lines. One of these is the hypotenuse, the other is the adjacent. The line it is not touching is the opposite.
What does the maths term Pythagoras mean?
1) A famous mathematician. 2) The word is often used for the relationship a2 + b2 = c2. This applies to a right triangle, assuming "c" is the longest side (the side opposite the right angle).
What is a right isosceles?
A right isosceles triangle is a type of triangle that has two sides of equal length and one angle measuring 90 degrees. The two equal sides are often referred to as the legs, while the third side, opposite the right angle, is called the hypotenuse. In a right isosceles triangle, the angles opposite the equal sides each measure 45 degrees, making it a specific case of both isosceles and right triangles. This triangle is commonly used in various mathematical and engineering applications due to its unique properties.
What is legs in math?
In mathematics, "legs" typically refer to the two sides of a right triangle that form the right angle. These legs are often denoted as the base and height when calculating the area of the triangle. In the context of trigonometry, they are also used to describe the sides in relation to the angles. The third side, opposite the right angle, is called the hypotenuse.
What are five characteristics of a TRIANGLE?
Triangle (geometry) IINTRODUCTIONTriangle (geometry), geometric figure consisting of three points, called vertices, connected by three sides. In Euclidean plane geometry, the sides are straight line segments (see Fig. 1). In spherical geometry, the sides are arcs of great circles (see Fig. 2). See Geometry; Trigonometry. The term triangle is sometimes used to describe a geometric figure having three vertices and sides that are arbitrary curves (see Fig. 3).IIPLANE TRIANGLESA Euclidean plane triangle has three interior angles (the word interior is often omitted), each formed by two adjacent sides, as ÐCAB in Fig. 1, and six exterior angles, each formed by a side and the extension of an adjacent side, as ÐFEG in Fig. 4. A capital letter is customarily used to designate a vertex of a triangle, the angle at that vertex, or the measure of the angle in angular units; the corresponding lower case letter designates the side opposite the angle or its length in linear units. A side or its length is also designated by naming the endpoints; thus, in Fig. 1, the side opposite angle A is a or BC.An angle A is acute if 0° < A < 90°; the angle is right if A = 90°; and it is obtuse if 90° < A < 180°. Because the sum of the angles of a triangle is 180°, a triangle can have at most one angle that is equal to or greater than 90°. A triangle is acute if all three of its angles are acute, as in Fig. 1; it is right if it has one right angle, as in Fig. 5; and it is obtuse if it has one obtuse angle, as in Fig. 4.A triangle is scalene if no two of its sides are equal in length, as in Fig. 1; isosceles if two sides are equal, as in Fig. 6; and equilateral if all three sides are equal, as in Fig. 7. The side opposite the right angle in a right triangle, HK in Fig. 5, is called the hypotenuse; the other two sides are called legs. The two equal sides of an isosceles triangle are also called legs, and the included angle is called the vertex angle. The third side is called the base, and the adjacent angles are called the base angles.If two sides of a triangle are of unequal size, the angles opposite are of unequal size; the larger side is opposite the larger angle. In the same way, if two angles are unequal, the sides opposite are unequal. Therefore, the three angles of a scalene triangle are of different sizes; the base angles of an isosceles triangle are equal; and the three angles of an equilateral triangle are equal (an equilateral triangle is also equiangular). The side opposite a right angle or an obtuse angle is the longest side of the triangle. see Trigonometry: Law of Sines for the exact relation between the sizes of the angles and sides of a triangle.In any triangle, an altitude is a line through a vertex perpendicular to the opposite side or its extension, for example, DX in Fig. 8a and 8b. A median is the line determined by a vertex and the midpoint of the opposite side, AN in Fig. 9. An interior angle bisector is the line through a vertex bisecting the interior angle at the vertex, AR in Fig. 10; similarly, an exterior angle bisector bisects the exterior angle at the vertex, AV in Fig. 10. A perpendicular bisector is a line perpendicular to a side at its midpoint, HK in Fig. 11. The terms altitude, median, and interior angle bisectorare also often applied to the line segment determined by the vertex and the intersection with the opposite side or its extension.The three altitudes of a triangle meet in a common point called the orthocenter, O in Fig. 8a and 8b. The three medians meet in a point called the centroid, M in Fig. 9. The centroid divides a median through it into two segments, and the segment having a vertex as endpoint is always twice as long as the other segment. The three angle bisectors meet in a point called the incenter (I in Fig. 10), and the three exterior angle bisectors meet in three points called the excenters, U, V, Wof Fig. 10. The incenter and the three excenters are centers of circles tangent to the sides or side extensions of the triangle. The three perpendicular bisectors meet in a point called the circumcenter, H in Fig. 11, which is the center of a circle passing through the three vertices.If a, b, c are the three sides of a triangle, and ha is the altitude through vertex A, the semiperimeter s is given by the formula s = y (a + b + c), and the area K by the formula K = yaha. Many other formulas interrelate the various parts of a triangle.IIISPHERICAL TRIANGLESMany properties of plane triangles have analogues in spherical triangles, but the differences between the two types are important. For example, the sum of the angles of a spherical triangle is between 180° and 540° and varies with the size and shape of the triangle. A spherical triangle with one, two, or three right angles is called a rectangular, birectangular, or trirectangular triangle. A spherical triangle in which one, two, or three sides are quadrants (quarter circumferences) is called a quadrantal, biquadrantal, or triquadrantal triangle.If two sides of a triangle are of unequal size, the angles opposite are of unequal size; the larger side is opposite the larger angle. In the same way, if two angles are unequal, the sides opposite are unequal. Therefore, the three angles of a scalene triangle are of different sizes; the base angles of an isosceles triangle are equal; and the three angles of an equilateral triangle are equal (an equilateral triangle is also equiangular). The side opposite a right angle or an obtuse angle is the longest side of the triangle.
What is one of the 2 sides of the right triangle that form the right angle?
In a right angled triangle, there are three sides. The longest of these is referred to as the hypotenuse. This longest side is always the side opposite the right angle. The other two sides are most often referred to as the "opposite" and "adjacent" depending on which other angle you are looking at. If you look at an angle other than the right angle, it will touch two lines. One of these is the hypotenuse, the other is the adjacent. The line it is not touching is the opposite.
Why hypotenuse more than other two sides?
We don't think about this very often, but it turns out that in any triangle, the order of the angles by length is the same as the order of the sides opposite them by length. What I mean is: -- the shortest side is opposite the smallest angle -- the medium side is opposite the medium angle -- the longest side is opposite the largest angle In a right triangle, the right angle has to be the largest angle(**). So the side opposite it ... called the hypotenuse ... has to be the longest side. ============================================================ (**) Here's why the right angle has to be the largest angle: In any triangle, the inside angles all add up to 180 degrees. In a right triangle, one of the angles is 90 degrees. That leaves only another 90 degrees to split up between the other two angles, so both of them must be less than 90 degrees.

What is a ambiguous triangle?
An ambiguous triangle, often referred to in the context of triangle congruence, arises in the case of the SSA (Side-Side-Angle) condition. This occurs when two sides and a non-included angle of a triangle are known, potentially leading to two different triangles, one triangle, or no triangle at all. The ambiguity stems from the fact that the given angle can correspond to two different configurations of the sides. Consequently, this situation does not guarantee a unique solution in triangle construction.
What is the definition for leg of a triangle?
There is no formal definition: it is any side of a triangle. Often, if the triangle has a horizontal base, then it is one of the sloped sides. In a right angled triangle, it is one of sides adjacent to the right angle. In an isosceles triangle, it is one of the equal sides.
Pythagoras is often described as what?
"The father of numbers."Pythagoras was an ancient Greek mathematician famous for his theorem for a right angle triangle.
What type of triangle can have one right angle?
A triangle that has one right angle is called a right triangle. In a right triangle, one of the interior angles measures exactly 90 degrees, while the other two angles are acute, adding up to 90 degrees. Right triangles are fundamental in trigonometry and are often used in various applications, including geometry and physics.
WHAT ARE THE EXAMPLE OF LA CONGRUENCE THEOREM?
The La Congruence Theorem, often referred to in the context of triangle congruence criteria, includes several key examples such as the Side-Side-Side (SSS) theorem, which states that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent. Another example is the Angle-Side-Angle (ASA) theorem, where two angles and the included side of one triangle are equal to the corresponding parts of another triangle, ensuring congruence. Additionally, the Side-Angle-Side (SAS) theorem asserts that if two sides and the included angle of one triangle are equal to those of another triangle, the triangles are congruent as well.
Is there such thing as a triangle with no right angles?
Of course. A triangle with a right angle is a very special case that you don't run intovery often, unless you happen to be doing a unit on right triangles in school.
What two shapes have a 90 degrees angle?
Two shapes that have a 90-degree angle are a rectangle and a right triangle. In a rectangle, all four angles are right angles, while a right triangle specifically features one angle that measures exactly 90 degrees. These shapes are fundamental in geometry and are often used in various applications.
