Use the image to answer the 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?
1 answer
Yes, the two indicated angles are adjacent. Adjacent angles are angles that share a common side and a common vertex, but do not overlap. In this case, angles AOB and COD share a common side (ray O) and a common vertex (point O), but do not overlap. Therefore, they are considered adjacent angles.
