Question

is $overline{rt}$ congruent to $overline{su}$? r -100 s -80 t -60 -40 0 u 20 yes no submit

Explanation:

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

Find the difference between coordinates of $R$ and $T$. $T=- 40$, $R = - 80$. So $RT=\vert-40-(-80)\vert=\vert-40 + 80\vert = 40$.

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

Find the difference between coordinates of $S$ and $U$. $S=-60$, $U = 20$. So $SU=\vert20-(-60)\vert=\vert20 + 60\vert=80$.

Step3: Compare lengths

Since $40
eq80$, $\overline{RT}$ is not congruent to $\overline{SU}$.

Answer:

no
