The prove, triangle AFC is congruent to triangle ABE. is achieved using SAS congruence theorem and CPCTC
How to complete the proof
The two column proof is written as follows
Statement Reason
AC ⊥ CEBF given
DF ⊥ FEBC given
AC ≅ DF given
CE ≅ FB given
∠ C ≅ ∠ F right angles are equal
CE + EB ≅ FB + BE Segment addition property
Δ ACB ≅ Δ DFB SAS congruence theorem
∠ A ≅ ∠ D CPCTC
