Question

is $overline{qs}$ congruent to $overline{pr}$?
(there is a number line with points p at 200, q at 400, r at 600, s at 800, and a mark at 1,000. below the question, there are two buttons: yes (with a hand cursor on it) and no, and a green submit button.)

Explanation:

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

Points Q at 400, S at 800. Length = $800 - 400 = 400$.

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

Points P at 200, R at 600. Length = $600 - 200 = 400$.

Step3: Compare lengths

Both lengths are 400, so congruent.

Answer:

yes
