Question

- Write a two-column proof. Given BF bisects angle AFC and angle CFD congruent angle BFC. Prove angle AFB congruent angle CFD

Answer 1

Since BF bisects angle AFC, AFB and BFC would be the same angle. The sum of AFB + BFC + CFD = 180°. And since CFD is congruent to BFC, All the three angles are the same. So AFB would be equal to CFD
