It has been proven that ΔWXV ≅ ΔYSV by SAS Congruency Postulate
How to solve the two column proof?
The two column proof to show that ΔWXV ≅ ΔYSV is as follows:
Statement 1: ΔWXZ ≅ ΔYSZX
Reason 1: Given
Statement 2: ∠WVZ ≅ ∠YVZ
Reason 2: Vertical angle theorem
Statement 3: ZV ≅ XV; WV ≅ YV
Reason 3: CPCTC
Statement 4: ∠WVX ≅ ∠YVZ
Reason 4: Opposite angle theorem
Statement 5: ΔWXV ≅ ΔYSV
Reason 5: SAS Congruency Postulate
