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).Determine whether the triangles are similar. If they are, write a similarity statement.
