Since by definition all right triangles have a 90 degree angle, we only need to know that one other angle is congruent to prove similarity. We remember that one of the tests for similarity is AA where if two angles of one triangle a...
Property 1: the sum of the squares of the two right sides of a right triangle is equal to the square of the hypotenuse. As shown in the figure, ∠BAC = 90°, then AB²+AC²=BC²(Pythagorean theorem); Property 2: in a right triangle, two acute angles complement each other. As...

The Cos Theta Formula is especially useful when working with right-angled triangles. In a right triangle, the Cosine of an angle will always be the length of the adjacent side divided by the length of the hypotenuse. This makes it a great tool for solving problems involving Cosine. The impo...
