Question

which figure fits this geometric notation? $overline{cd}$

Explanation:

Step1: Recall geometric notation

The notation $\overline{CD}$ represents a line - segment with endpoints C and D.

Step2: Analyze figures

The first figure is a line (extends infinitely in both directions), the second is a line - segment (has two endpoints C and D), and the third is a ray (extends infinitely in one direction starting from C). So the second figure matches the line - segment notation $\overline{CD}$.

Answer:

The second figure (the one with endpoints C and D and a line - segment between them).
