Similar Triangles • You can always prove two triangles are similar by showing: – 1: all angles are congruent – 2: all sides are proportional – BUT, there are simpler, shorter methods! AA Similarity Postulate • If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. SAS Similarity Theorem • If an angle of one triangle is congruent to an angle of another triangle and the sides including those angles are in proportion, then the triangles are similar. SSS Similarity Theorem • If the sides of two triangles are in proportion, then the triangles are similar.
