Are points that lie on the same plane
A coplanar points
Consists of the endpoints A and B and all points on AB that are between A and B
THe Segment AB
Consits of the endpoints A and B and all points on AB that lie on the same side of A as B
ray AB
is the point of points that the figures have in common
