To determine which angles are adjacent to "angle r," we need to recall that adjacent angles are two angles that share a common vertex and have a common side.
Based on the options provided:
A. angle p B. angle s C. angle q
Since I cannot see the diagram of the angles, I can't definitively say which angles are adjacent to angle r without further context. However, if you know the positions of angle r relative to angles p, q, and s, you can identify which ones are adjacent by checking which share a common side and vertex with angle r.
Please provide more context or the arrangement of the angles if you need a specific answer!
