Which pair of angles shares ray a-f as a common side?

Given : FA is a ray.

Find out the pair of angles share the common side FA.

To proof

As shown in the diagram

∠ BAF and ∠DAF  are th.e pair of angles shares FA as a common side

REASON

Adjacent Angles are those angles that share a common side, a common vertex, and no common interior points.

as ∠ BAF and ∠DAF  shares common vertex A and  common side FA.

Therefore

∠ BAF and ∠DAF  are th.e pair of angles shares FA as a common side
