Question

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

Explanation:

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

$KM=\vert - 520-(-560)\vert=\vert - 520 + 560\vert = 40$

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

$JL=\vert - 540-(-580)\vert=\vert - 540 + 580\vert = 40$

Step3: Check congruence

Since $KM = JL=40$, the line - segments are congruent.

Answer:

yes
