POINT We may think of a point as a "dot" on a piece of paper. We identify this point with a number or letter. A point has no length or width, it just specifies an exact location. Example: The following
LINE Has one dimension. It extends without end in two directions. It is represented by a line with two arrowheads.
PLANE Has two dimensions. It is represented by a shape that looks like a floor or wall. It extends without end.
COPLANAR POINTS Points that lie on the same plane.
COLLINEAR POINTS Points that lie on the same line.
