Geometry Sections 6.4 and 6.5 Prove Triangles Similar by AA Prove Triangles Similar by SSS and SAS Angle-Angle (AA) Similarity Postulate • If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar Examples • Page 384 • Problems # 3-8, 9, 11 Side-Side-Side (SSS) Similarity Theorem • If the corresponding side lengths of two triangles are proportional, then the triangles are similar Side-Angle-Side (SAS) 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 Examples • Page 392 • Problems # 5, 7, 11 Assignment • • • • • Sections 6.4 and 6.5 Page 384 Problems # 10-14 even, #34 Page 392 Problems #6, 8, 10, 18-23
