All of the central angles (non-overlapping) of a circle sum to 360

 

"Vertical angles are the angles that are opposite each other when two straight lines intersect. (Technically, these two lines need to be on the same plane) Vertical angles are congruent (in other words they have the same angle measuremnt or size"

 

supplementary angles sum to 180    Clomplementary angles sum to 90
