Consider the diagram to the right below and complete the proof below

a) reflexive , sas , cpctc

b) segment addition postulate, transitive , sas

c ) sss, sas , cpctc

d) transitive , cpctc , sas

The Proof with Statement and Reason are as follow.

A) Reflexive , SAS , CPCTC.

Step-by-step explanation:

Given:

BA ≅ DC

∠BAC ≅ ∠DCA

To Prove:

BC ≅ DA

Proof:

In ΔBCA and ΔDAC

Statement                                                 Reasons

1. BA ≅ DC                                          1. Given

∠BAC ≅ ∠DCA

2. AC ≅ CA                                         2. Reflexive Property

3.  ΔBCA ≅ ΔDAC                              3. S-A-S test

4. BC ≅ DA                                         4. CPCTC
