Question

what is the name of this figure?

Explanation:

A ray is a part of a line that has one endpoint and extends infinitely in one direction. In the given figure, point \( D \) is the endpoint, and the line extends infinitely in the direction of point \( C \) (as indicated by the arrow). So this figure is a ray, specifically ray \( DC \) (or \( \overrightarrow{DC} \)).

Answer:

Ray \( DC \) (or \( \overrightarrow{DC} \))
