Lines, line segments, and rays - Practice

A line is a straight path that extends infinitely in both directions. It has no endpoints.

A line segment is a part of a line that has two endpoints. It is a fixed length.

A ray is a part of a line that starts at one endpoint and extends infinitely in one direction.

A line has no endpoints.

A line segment has two endpoints.

A ray has one endpoint.

No, a line cannot be measured because it extends infinitely.

Yes, a line segment can be measured because it has a fixed length.

No, a ray cannot be fully measured because it extends infinitely in one direction.

An example of a line is the edge of a ruler if you imagine it extending forever.
