AA (Angle-Angle) Similarity Postulate

If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar

SSS (Side-Side-Side) Similarity Postulate

If the three sides of one triangle are proportional to the three corresponding sides of another triangle, then the two triangles are similar

SAS (Side-Angle-Side) Similarity Postulate

If two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar
