Question

what is the name of this figure?

Explanation:

A ray has one endpoint and extends infinitely in one direction. The figure here has endpoint \( Q \) and extends infinitely through \( P \) in the left - ward direction, so it is a ray (specifically ray \( QP \) or we can refer to it by its direction - related naming considering the arrow). The symbol for a ray is usually with an arrow on one end. Looking at the figure, the arrow is on the left - extending side from \( Q \) through \( P \), so it's a ray.

Answer:

Ray (specifically, the ray can be named as \(\overrightarrow{QP}\) where \( Q \) is the endpoint and it extends through \( P \) infinitely)
