Answer:
neither ; their slopes aren't the same and aren't reciprocals.
Step-by-step explanation:
neither ; their slopes aren't the same and aren't reciprocals.
I took the test, I got the question right.
PRU and STQ are not congruent because they aren’t the same size.
No, because they aren’t the same size.
<u>Step-by-step explanation:</u>
Both PRU and STQ triangles aren't in the same size, So it is not congruent. Triangles are congruent if two pairs of corresponding angles and a couple of inverse sides are equivalent in the two triangles.
If there are two sets of corresponding angles and a couple of comparing inverse sides that are not equal in measure, at that point the triangles are not congruent.
