Question

which defines ray? a piece of a line with two endpoints all points equidistant from a given point two line segments with a common endpoint a piece of a line that starts at the endpoint and extends indefinitely in one direction

Explanation:

A ray is a fundamental geometric concept. It has one endpoint and extends infinitely in one direction. A piece of a line with two endpoints is a line - segment. All points equidistant from a given point form a circle. Two line - segments with a common endpoint refer to angles or other geometric combinations.

Answer:

a piece of a line that starts at the endpoint and extends indefinitely in one direction
