Question

is $overline{km}$ congruent to $overline{jl}$?
-580 -560 -540 -520 -500
j k l m
yes no

Explanation:

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

The coordinates of $K=-560$ and $M = - 520$. The length of $\overline{KM}$ is $|-520-(-560)|=|-520 + 560|=40$.

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

The coordinates of $J=-580$ and $L=-540$. The length of $\overline{JL}$ is $|-540-(-580)|=|-540 + 580|=40$.

Step3: Check congruence

Since the lengths of $\overline{KM}$ and $\overline{JL}$ are equal, they are congruent.

Answer:

yes
