Question

is $overline{km}$ congruent to $overline{ln}$?
-600 -400 -200 0 200 400
yes no

Explanation:

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

The coordinates of $K=-400$ and $M = 0$. The length of $\overline{KM}=|0 - (-400)|=400$.

Step2: Calculate the length of $\overline{LN}$

The coordinates of $L=-200$ and $N = 200$. The length of $\overline{LN}=|200-(-200)| = 400$.

Step3: Compare the lengths

Since the length of $\overline{KM}=400$ and the length of $\overline{LN}=400$, the two line - segments are congruent.

Answer:

yes
