A ray is a geometric figure that has no height or width. It only has an indefinite length. The name of a ray must always include its origin point. We need two rays to form an angle.

A ray is a shape that starts at one point and extends forever in one direction. To identify a ray in a picture, look for a line that has one endpoint (the point where the ray starts) and an arrow on the other end (to show that it keeps going).

A ray is a geometric object that has one endpoint from which it extends infinitely. It can be thought of as being part of a line with the key difference being that a line extends infinitely in two directions, while a ray only extends infinitely in one direction.

A ray (in geometry) is a line characterized by a defined starting point (the terminus) with infinite length in only one particular direction (no ending point).
