The basic concepts of "line" and "point" can be used to define a ray. A ray is a portion of a line that starts at a point and extends in a particular direction.

A
An angle is the intersection of two rays at a common point.

B
An angle is the figure formed by two rays that lie on the same line.

C
An angle is a special kind of ray that points in two particular directions.

D
