Question

is $overline{st}congoverline{tu}$?
s 61 62 t 63 64 u 65 66 67
yes no

Explanation:

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

The coordinates of $S = 61$ and $T=63$. The length of $\overline{ST}$ is $|63 - 61|=2$.

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

The coordinates of $T = 63$ and $U = 65$. The length of $\overline{TU}$ is $|65 - 63|=2$.

Step3: Check for congruence

Since $ST = TU=2$, the line - segments are congruent.

Answer:

yes
