directions - name each geometric
11)
12)
ray
line dc
line
segment
cd
ray cd
plane dc

Explanation:

Step1: Recall geometric - figure definitions

A line extends infinitely in both directions, a ray has one endpoint and extends infinitely in one direction, and a line - segment has two endpoints.

Step2: Analyze the first figure

The figure with endpoints labeled \(C\) and \(D\) and extending infinitely in one direction is a ray. It can be named as ray \(CD\) (where \(C\) is the endpoint).

Step3: Analyze the second figure

The figure with an arrow - head indicating it extends infinitely in one direction is also a ray.

Answer:

1. Ray \(CD\)
2. Ray (assuming the endpoint and direction are clear from the figure in the context, but without a label for the endpoint in the visible part of the image, we just say ray as the general answer for the type of geometric figure)
