Given: ∠CBA ≅ ∠FBA; ∠CAB ≅ ∠FAB Prove: ΔBCA Is-congruent-to ΔBFA
Triangles C B A and F B A share common side B A. Angles C B A and A B F are congruent. Angles C A B and B A F are congruent.
Complete the missing parts of the paragraph proof.
Proof:
We know that angle CBA is congruent to angle FBA and that angle CAB is congruent to angle FAB because . We see that is congruent to by the reflexive property of congruence. Therefore, we can conclude that triangle BCA is congruent to triangle BFA because .
