Document Summary

Answer these questions on answer sheet 1. (15) Given : p m is the perpendicular bisector of ab. Given : ab = cd, ad = bc, 1 is a right angle. Given : ab = bc, d is midpoint of ab, e is midpoint of bc. Statements: ab = bc, d is midpoint of ab. 2 ab, be = 1: bd = 1, be = 1. 2 ab: bd = be, abe = cbd. Answer these questions on answer sheet 2. (20) For each of the following pairs of triangles: If the pair is congruent, name the congruence and give the appropriate triangle congruence property (e. g. abc = def by sss). Otherwise, state that there is not enough information to determine if the triangles are congruent. Fill in the missing steps in the proof below. Given : abc is isosceles with ab = bc, bd is the angle bisector of abc. Prove : d is the midpoint of ac.
