Given: rstu is a parallelogram. trs rxs rtu rxu see picture

Step-by-step explanation:

We have been given a graph of a parallelogram and we are asked to find which triangle is congruent to triangle TRS.

Since we know that the opposite sides of a parallelogram are equal, so TU = RS.

Since the alternate interior angles formed by two parallel and a transversal is equal. We can see that line TU is parallel to line RS and TR will be our transversal, therefore, angles formed inside the parallel lines and on the opposite sides of transversal will be equal.

By alternate interior angles:

We can see that in triangle TRS and RTU segment RT equals to itself.

Therefore, by SAS congruence postulate and option B is the correct choice.

the first dot plot best represents the data
