Example. ABC ≅ XYZ A B C ≅ X Y Z. Two sides and the included angle are congruent. AC = ZX (side) ∠ ∠ ACB = ∠ ∠ XZY (angle) CB = ZY (side) Therefore, by the Side Angle Side postulate, the triangles are congruent.You can't say these triangles are similar by SSA because that is not a criterion for triangle similarity. However, because these are right triangles, you know that the third side of each triangle can be found with the Pythagorean Theorem. For the smaller triangle: 12 2 + x 2 = 15 2 → x = 9. For the larger triangle: 36 2 + x 2 = 45 2 → x = 27.Definition: Triangles are similar if two sides in one triangle are in the same proportion to the corresponding sides in the other, and the included angle are equal.

Identify the sides and angle that can be used to prove triangle similarity using SSS similarity theorem and SAS similarity theorem. Using Triangle Similarity Theorems Complete the steps to prove theorems involving similar triangles. Solve for unknown measures of similar triangles using the side splitter theorem and its converse. Example: these two triangles are similar: If two of their angles are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°. In this case the missing angle is 180° − (72° + 35°) = 73°. So AA could also be called AAA (because when two angles are equal, all three angles must be equal).
