Question

which choice names an endpoint? 2. choose the best answer. a ___ consists of two endpoints and all the points in between them.

Explanation:

Step1: Recall geometric - figure definitions

An endpoint is a point at the end of a line segment or a ray. A line segment has two endpoints, a ray has one endpoint, a line has no endpoints, and a plane is a flat surface.

Step2: Analyze each option for first question

• $\overleftrightarrow{AC}$ is a line, which has no endpoints.
• $\overrightarrow{BC}$ is a ray with endpoint $B$, but we are looking for a single - point name as an endpoint.
• $A$ is a point and can be an endpoint of a line segment or a ray.
• $\overline{AB}$ is a line segment with endpoints $A$ and $B$, but it is not an endpoint itself.

Step3: Analyze second question

A line segment consists of two endpoints and all the points in between them. A plane is a two - dimensional flat surface, a point is a location, and a ray has one endpoint and extends infinitely in one direction.

Answer:

1. C. $A$
2. A. line segment
