Pupils can practise proving that two or more triangles are similar, and apply similarity to find unknown side lengths. The similarity and congruence worksheets ask them to determine whether pairs of triangles are congruent in increasingly ...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).Thus my friend’s tents and my tents are similar. 8.3 Proving Triangle Similarity by SSS and SAS.
