Question

is $overline{pr}congoverline{qs}$?
p q r s
200 210 220 230 240 250 260 270
yes no

Explanation:

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

$PR = 220 - 200=20$

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

$QS = 230 - 210 = 20$

Step3: Compare lengths

Since $PR = QS = 20$, $\overline{PR}\cong\overline{QS}$.

Answer:

yes
