Theorem 7-3: Similarity in Right Triangles Theorem.

Using properties of perpendicular bisectors and angle bisectors. Perpendicular bisectors. What do we know about the right triangles formed when we draw an isosceles triangle that has a bisector of its vertex angle?. If triangles are similar are other things similar as well. Proportional Parts Conjecture. If two triangles are similar, then the length of the corresponding altitudes, medians, and angle bisectors are proportional to the lengths of the corresponding sides. This shows similar Triangles. Using Congruent Triangles. Congruent triangles have congruent corresponding parts. So, if you can prove the two triangles are congruent then you know their corresponding parts must be congruent as well.. Objective. :.
