What are trigonometric functions?
Let's look at right triangles for a moment. In any right triangle, the hypotenuse is the side opposite the right angle. There exist three ratios (and their inverses) as regards the length of the sides of the right triangle. These are opposite/hypotenuse (called the sine function), adjacent/hypotenuse (called the cosine function), and opposite/adjacent (called the tangent function). The inverse of the sine is the cosecant, the inverse of the cosine is the secant, and the inverse of the tangent is the cotangent. The abbreviations for these functions are, sin, cos, tan, csc, sec and cot, respectively. What is underneath this idea is that for any (every!) right triangle, there is a fundamental relationship or ratio between the lengths of the sides for all triangles with the same angles. For instance, if we have a triangle with interior angles of 30 and 60 degrees (in addition to the right angle), regardless of what size it is, the ratio of the lengths of the sides is always the same. And the trigonometric functions express the ratios of the lengths of the sides.
What is Law of the sine?
The law of sines is a statement about arbitrary triangles in the plane.The law of sines states that in any right triangle, the ratio of the opposite side length to the length of the hypotenuse (relative to an acute angle) is always relative to the size of the angle. Put more simply, it means that if you take the sine of an angle, the value will be equal to the length of the opposite side divided by the length of the hypotenuse. The practical application of this is when you know the length of only one side and the measure of one angle (other than the right angle) you can determine the other sides and the remaining angle.The law of sines states that in any right triangle, the ratio of the opposite side length to the length of the hypotenuse (relative to an acute angle) is always relative to the size of the angle.

In an isosceles triangle one base angle equals 73 find the size of the vertex angle?

What is the size of an acute angle?
An acute angle is larger than than 0 degrees but less than 90 degrees (a right angle).
How do you divide a triangle into six equal parts?
make six equilateral triangles depending on the size edit: If it is an equilateral triangle, draw a line from each corner to the centre of the opposite side.
What are the different kinds of angles and triangle according to size and its angles?
Angles: acute angle, obtuse angle, right angle Triangles: isosoles triangle, scalene triangle, equadrital triangle, right triangle, acute triangle, obtuse triangle
Interior angle is 30 degrees between two sides that are 9 centimeters and 8 centimeters What is the other two angles and the perimeter of the triangle?
angle a= 87.3819 DEG. (approx.) angle b= 62.6181 DEG. (approx.) angle c= 30 deg. side opposite angle a= 9 cm (given) side opposite angle b= 8 cm (given) side opposite angle c= 4.5047 cm this triangle is almost a 30, 60, 90 better known as a special right triangle where the side opposite the right angle is twice the size of the side opposite the 30 deg. angle so the side opposite angle b would be: 9/2 times the square root of 3. to solve this problem (since this triangle is not really a right triangle) you must use the law of cosines coupled with the law of sines in order to solve this problem.
In a scalene triangle the longest side is opposite the angle with the largest measure true of false?
True. In any triangle, the longest side is always opposite the largest angle; the shortest side is always opposite the shortest angle; and the middle length side is always opposite the middle size angle. In an isosceles triangle, there is no middle length side; and the two sides of equal length are opposite the angles of equal size. In an equilateral triangle, all sides are the same length, as are all the angles.
Make a right angled isosceles triangle This is a triangle with a right angle and two equal anles that are not right angles What is the size of these non right angles?
45 degrees. they have to be the same angle, because they are opposite equal lengths, and when added together they must equal 90, so as to make the total of the angles 180.
What is the size of a hypotenuse?
The hypotenuse is the longest side of a right angle triangle.
Can a triangle have to right angles if yes what would be the size of the third angle?
A right angle triangle can only have 1 right angle of 90 degrees and its 3 interior angles add up to 180 degrees
Why do trigonometric ratios do not depend on the size of the right triangle?
Because a right angle will always measure 90 degrees no matter what the dimensions of the triangle are.
What is the size of two angles that meet at a right angle?
The combined size of the other two angles of a right triangle is 90 degrees.
Oblique triangle given two sides and an angles opposite one of th em?
"Two sides and the angle opposite one of them" doesn't uniquely define a triangle. That is,there can be two or more triangles with different size, or shape, or area that have the sametwo sides and the same angle opposite one of them.In order to use two sides to define a unique triangle, you also have to give the angle between them.
Could a right triangle ever become an equilateral triangle?
No. Regardless of the size the Hypotenuse (the side opposite the right angle) would always be bigger athn either of the other two sides. It has to be as the sum of its square is always equal to the sum of the squares of both of the other two sides.
Is an equilateral right triangle possible?
No, that's not possible. Consider these facts: -- all three angles of any triangle always add up to 180 degrees -- all three angles in an equilateral triangle have to be the same size -- a right triangle has a right angle in it; a right angle is 90 degrees An equilateral right triangle would need three right angles in it, and they would add up to 270 degrees. As we said earlier: Impossible.
If a quadrilateral has a right angle is it a triangle?
No because a quadrilateral has 4 sides whereas a triangle has 3 sides.
