Question

Please help!!

Given: 2 ≅ 5, AB ≅ DE
Prove: BC ≅ EC

Answer 1

Statements | reasons
1. 2 ≅ 5, AB ≅ DE 1. given
2. 3 ≅ 4 2. vertical angle thm.
3. △BAC ≅ △CDE 3. AAS
4. BC ≅ EC 4. CPCTC


thm. = theorem

CPCTC = Corresponding parts of congruent triangles are congruent

sorry if it looks a bit strange
