Because a right angle will always measure 90 degrees no matter what the dimensions of the triangle are.
You can use your trigonometric functions (sine, cosine, and tangent).
By using trigonometry that is applicable to a right angle triangle.
That will depend on what type of triangle it is as for example if it is an isosceles triangle then it will form two congruent right angle triangles.
a right triangle has one right angleA triangle with a right angle is a right triangle.
A triangle with 1 right angle is a right angle triangle.
Using trigonometric ratios.
They may be defined as the ratios of the lengths of sides of a right angled triangle, relative to either of the other angles.sine = opposite/hypotenusecosine = adjacent/hypotenusetangent = opposite/adjacentcosecant = hypotenuse/oppositesecant = hypotenuse/adjacentcotangent = adjacent/opposite.
There are six trigonometric ratios. Although applicable for any angle, they are usually introduced in the context of a right angled triangle. The full names of the main three ratios are sine, cosine, tangent. The other three ratios are reciprocals, which are cosecant, secant and cotangent, respectively.Suppose ABC is a triangle which is right angled at B. Thus AC is the hypotenuse.sin(A) = BC/AC = cos(C)cos(A) = AB/AC = sin(C)tan(A) = BC/AB
The trigonometric functions give ratios defined by an angle. Whenever you have an angle and a side in right triangle, you can find all the other angles and sides using the six trigonometric functions and their inverses. The link below demonstrates the relationship between functions.
Trigonometric ratios are ratios of the sides of a right triangle, involving the lengths of the sides and the angles of the triangle. The main trigonometric ratios are sine, cosine, and tangent, which are abbreviated as sin, cos, and tan respectively. These ratios are used in trigonometry to relate the angle of a right triangle to its side lengths.
You can use them to find the sides and angles of a right triangle... just like regular trigonometric functions
You can use your trigonometric functions (sine, cosine, and tangent).
It depends on the details of the specific triangle.
All the trigonometric functions are derived from the right angled triangle. If we consider the three sides (AB, BC, CA) of a triangle and the included angle. There is a possibility of getting six functions based on the ratios like AB/AC, BC/AC, AB/BC, BC/AB, AC/BC, AC/AB . So we will have six trigonometric functions
Sine of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
The three basic trigonometric ratios are sine (sin), cosine (cos) and tangent (tan) They are found by comparing two of the three sides of a right triangle. The hypotenuse is the the longest side of the right triangle, and is opposite the right angle. The other two sides are the legs. One leg is adjacent to an angle, and the other is opposite the angle. The three ratios are sin(x) = opposite/hypotenuse cos(x) = adjacent/hypotenuse tan(x) = opposite/adjacent =================
They are called Pythagorean triples such as 2, 4 and 5
