Question

what is the name of this figure?

Explanation:

A ray is a part of a line that has a fixed starting point (the endpoint) and extends infinitely in one direction. In the given figure, there is a starting point (the left - most dot) and the line extends infinitely towards the direction of the arrow. The ray can be named using its endpoint and another point on it, so this figure is a ray, specifically ray \( \overrightarrow{FG} \) (or ray \( FG \) in a more simplified naming where the direction is indicated by the order of the points, with \( F \) being the endpoint and \( G \) being a point on the ray).

Answer:

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