Question

which segment is congruent to $overline{cd}$?

Explanation:

Step1: Recall congruent - segment definition

Two segments are congruent if they have the same length.

Step2: Identify segment lengths

From the figure, $CD = 6.4$, $DA=6.4$, $BC = 6.5$, $AB = 6.5$.

Step3: Find congruent segment

Since $CD = 6.4$ and $DA = 6.4$, segment $\overline{DA}$ is congruent to $\overline{CD}$.

Answer:

B. $\overline{DA}$
