... If 2 angles of one triangle are congruent to 2 angles of another triangle then the triangles are similar. Note: There is no need to investigate the AAA Similarity Theorem, since it is equivalent to the AA Similarity Theorem. 9. Investigation 2 Is SSS a Similarity Shortcut? If three sides of one tria ...
