Question

is $overline{fg}$ congruent to $overline{ef}$?

Explanation:

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

$FG=20 - 18=2$

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

$EF=18 - 16 = 2$

Step3: Check congruence

Since $FG = EF=2$, $\overline{FG}$ is congruent to $\overline{EF}$.

Answer:

yes
