Question

1. what is the name of this figure?

Explanation:

A line segment has two endpoints, but a line extends infinitely in both directions, and a ray has one endpoint and extends infinitely in one direction. This figure has two arrowheads, meaning it extends infinitely in both directions, and it passes through points B and C, so it's a line (specifically line BC or line CB).

Answer:

Line (or Line BC, Line CB)
