I need help with geometric proofs.

Prove that ABDC = ABDE when Statement Reason 1. BD bisects /B and BD_L CE 5 points B D 2. Prove that ZA= ZE Statement When BD LAB , BD LDE Reason BC = DC 5 points C Prove they are congruent Triangles and then think about what that means. Last step is the hardest.3. Given: E is the midpoint of DC Statement Reason and AB 6 points Prove: ADEA = ACEB D B B Statement Reason 4 A 6 points Given: AC=CD, LB and ZE are right angles Prove: AABC=ADEC
