There is something wrong with this definition for a pair of vertical angles: “If AB and CD intersect at point P,then APC and BPD are a pair of vertical angles.” Sketch a counterexample to show why it is not correct. Can you add a phrase to correct it?
- Umm, for the counterexample, would it be correct if I draw an intersecting line but for APC and BPD I make the angle different?
