WebAug 26, 2024 · For example, these triangles are similar because their angles are congruent. Isosceles triangles are triangles with two equal sides, and thus two equal angle measures. For example, both of these triangles are isosceles, since they have two equal sides and angles. This triangle has two angles with equal measures of 75∘. WebIf two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion. Picture three angles of a triangle floating around. WebIf you have two right triangles and the ratio of their hypotenuses is the same as the ratio of one of the sides, then the triangles are similar. (You know the missing side using the Pythagorean Theorem, and the missing side must also have the same ratio.) So I suppose that Sal left off the RHS similarity postulate. 2 comments ( 5 votes) Flag cupid island gpo
