Question

An illustration shows four rays with points near the arrows labeled A, B, C, and D in a clockwise direction emerging from a common point labeled O. The angle A O B is marked as 40 degrees and angle C O D is marked as 50 degrees.

Are the two indicated angles adjacent? Why or why not?

Answer 1

Yes, the two indicated angles, angle A O B and angle C O D, are adjacent because they share a common ray (O) and vertex (O).
