Question

is $overline{kl}equivoverline{lm}$?

Explanation:

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

Use distance formula on number - line: $KL=\vert20 - (- 20)\vert=\vert20 + 20\vert = 40$

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

Use distance formula on number - line: $LM=\vert40 - 20\vert=20$

Step3: Compare lengths

Since $40
eq20$, $\overline{KL}
ot\equiv\overline{LM}$

Answer:

no
