Question

is $overline{qs}$ congruent to $overline{pr}$?
(there is a number line with points p at 0, q at 200, r at 400, s at 600, and a mark at 800. below are two buttons: yes and no, with a hand pointing to no.)

Explanation:

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

Q is at 200, S is at 600. Length = $600 - 200 = 400$.

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

P is at 0, R is at 400. Length = $400 - 0 = 400$.

Step3: Compare lengths

Since both lengths are 400, they are congruent.

Answer:

yes
