Coplanar points: Points that lie in the same plane.
Plane: a flat, 2D surface with no height.
1. Three colinear points: A, B, E
2. Four coplanar points: A, B, C, E
3. A plane containing E: plane S
4. Two points and a line that lie in Plane T: Points F & G, Line L
5. Two planes that contain l: S and T
