An illustration shows three rays labeled A, B, and C emerging from a common point labeled O. The points A, O, and C fall on a straight line. Angle C O B is marked as 1 and angle B O A is marked as 2.
Are the two indicated angles adjacent? Why or why not?

Yes, the two angles share a common ray and vertex.
Adjacent angles are defined as two angles that share a common side (ray) and a common vertex. In this case, both angles C O B (angle 1) and B O A (angle 2) share the common ray OB and the common vertex O. Therefore, they are indeed adjacent angles.
