Question

A part of a line that starts at one endpoint and extends forever in one direction is a(n):

Answer 1

The correct answer is “RAY”

Explanation:

This is the part of a line that has a stable, permanent, starting point but no an ending one. It goes off in a particular direction to infinity, possibly through another point or more than one as well. When naming it, a small ray on top of its ray must be denoted.

Answer 2

A part of a line that starts at one endpoint and extends forever in one direction is a(n): RAY

Explanation:

Ray--

A ray is a part of a line that starts at a point and goes infinitely in any direction to infinity i.e. there is no end point for the other end. i.e. it is called a line with one end-point.

Also, it use two undefined terms of mathematics: Point and Line.

Two ray starting with the same end-point and going to different direction form an angle.
