Question

is $overline{st}$ congruent to $overline{rs}$?
r 19 20 s 21 22 t 23 24
yes no

Explanation:

Step1: Calculate length of $\overline{RS}$

$RS=21 - 19=2$

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

$ST=23 - 21=2$

Step3: Compare lengths

Since $RS = ST=2$, the segments are congruent.

Answer:

yes
