6
Congruence vs. Similarity Similarity implies that only the angles are of equal measure and the sides are proportional

7
AA Similarity Postulate Two triangles are similar if two pairs of corresponding angles are congruent

8
AA Similarity Postulate A B C D E F

9
SAS Similarity Postulate Two triangles are similar if two pairs of corresponding sides are proportional and the included angles are congruent

10
SAS Similarity Postulate A B C D E F 4 6 8 12

11
SSS Similarity Postulate Two triangles are similar if all three pairs of corresponding sides are proportional.
