Supplementary Angles that are Linear Pair

This post-it dispenser can be used as an example of a supplementary angle that is not a linear pair because the two angles add up to a 180 degree straight line. The base of the dispenser is the 180 line and the post it branching out is the linear pair. This is an original picture. Post-its are used as office supplies and by students marking books.

Three or more Coplanar Parrallel Lines

Tennis courts use three or more co planar parallel lines in their service areas. Those lines if they were to continue would never touch, making them parallel. They are on the same court which in this case is the plane. Tennis is a sport widely played around the world by thousands.
