Write a two-column proof.
Given: ⎯→⎯⎯⎯⎯b d vector bisects ∠angle c b e.
Prove: ∠≅∠angle , eh b d , approximately equal to angle , f b d
Line AE falls from left to right and line FC rises from left to right. The two lines intersect at point B. Points A and F are to the left of point B and points C and E are to the right of point B. Ray BD bisects angle CBE.
