Question

are $overline{tu}$ and $overline{st}$ congruent?
r s i u v
75 m 78 m 78 m 80 m
yes no

Explanation:

Step1: Find length of $\overline{TU}$

The length of $\overline{TU}$ is given as 78 m.

Step2: Find length of $\overline{ST}$

The length of $\overline{ST}$ is given as 78 m.

Step3: Check congruence

Two line - segments are congruent if they have the same length. Since length of $\overline{TU}=78$ m and length of $\overline{ST}=78$ m, they are congruent.

Answer:

yes
