Similarity Postulates Sections 6.4 & 6.5
Angle-Angle Similarity Postulate (AA) • If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar.
Side-Side-Side Similarity Theorem • If the corresponding side lengths of two triangles are proportional, then the triangles are similar.
Side-Angle-Side Similarity Theorem • If an angle of one triangle is congruent to an angle of a second triangle and the lengths of the sides including these angles are proportional, then the triangles are similar.
