Question

name the figure
line kl
ray kl
line lk
ray lk

Explanation:

A ray has one endpoint and extends infinitely in one direction. In the given figure, the endpoint is L and it extends through K, so it is named ray LK. A line extends infinitely in both directions and naming order doesn't matter for a line (line KL and line LK are the same), but this is not a line. For a ray, the order matters as it indicates the starting - point and the direction of extension.

Answer:

ray LK
