If a diagram is unmarked, can you

angles are adjacent?

angles or segments are congruent?

angles are adjacent and supplementary?

an angle is a right angle?

angles are vertical angles?

angles are complementary?

Both pairs of vertical angles (four angles altogether) always sum to a full angle(360°). In the figure above, an angle from each pair of vertical angles are adjacentangles and are supplementary (add to 180°). For example, in the figure above, m∠JQL + m∠LQK = 180°.

I answered because answering is like the dog that walked when the cat scratched the tree after the fish walked to the store on a cold summers day
