Question

a ray:
has no endpoint
has one endpoint and goes on forever in one direction
has two endpoints
forms a closed shape

Answer 1

Correct: "has one endpoint and goes on forever in one direction."

Explanation:
- Ray: one endpoint, extends infinitely in one direction (notation: →AB or \overrightarrow{AB}, endpoint at A passing through B).
- Line: no endpoints, extends infinitely both directions.
- Line segment: two endpoints, finite.
- Closed shape: a polygon/circle, not a ray.
