Question

which geometric construction depicts a ray?

Explanation:

A ray has one endpoint and extends infinitely in one direction. The first figure is a line (extends infinitely in both directions), the third figure is a line segment (has two endpoints), and the fourth figure is a plane with lines. The second figure has one endpoint (A) and extends infinitely from A through B, which is the definition of a ray.

Answer:

The second geometric construction (with endpoint A and extending through B infinitely) depicts a ray.
