By using trigonometry or using Pythagoras' theorem for a right angle triangle.
the Pythagorean theorem is the following:a2 + b2 = c2So for example:then you will solve for whatever side you are searching forbut for this theorem to work it must be a right triangle! and "c" must be the side across from the right angle
If its angles are 45, 45 and 90 degrees then it is an isosceles right angle triangle and its properties can be worked out using Pythagoras' theorem and trigonometry
If its angles are 45, 45 and 90 degrees then it is an isosceles right angle triangle and its properties can be worked out using Pythagoras' theorem and trigonometry
The Triangle Angle-Sum Theorem just states that the angles of any triangle must add up to be 180 degrees. For example, suppose you have triangle ABC and m<A=65 and m<B=36. Well, what is the measure of angle C? We can solve for <C by using the Triangle Angle-Sum Theorem. All we do is set up an equation like so: m<A + m<B + m<C = 180. Now just fill in the values we know, so the equation is now: 65 + 36 + x = 180. Now simply and solve for x and you get that x=79. Just to check you work, add up 65, 36, and 79 and you will get 180.

a circle is 360 degrees. so whatever exterior angle u have u can subtract it from 360 to see what the interior angle is!
A triangle with one right angle and two acute angles is called a right triangle. In a right triangle, one of the angles measures 90 degrees, making it a right angle, while the other two angles are acute, meaning they measure less than 90 degrees each. The Pythagorean theorem can be applied to solve for the lengths of the sides of a right triangle.
This can only be done in the case of a right angle triangle. If 'x' represents one of the sides then the length of the two other sides must be known.
The Pythagorean Theorem states that a2 + b2 = c2, where c is the longest side (opposite the right angle). Replace the sides you know, and solve for the other side.
