Geometry

The answer is C. .

 

1. Recall the notations for different geometric figures:

: This notation represents a ray. A ray has one endpoint (the first letter in the notation, in this case ) and extends infinitely in the direction of the second - named point (). The given figure has two arrow - heads, so it is not a ray.

 

: This notation represents a line segment. A line segment has two endpoints ( and ) and has a definite length. The given figure extends infinitely in both directions, so it is not a line segment.
