Answer:

They are complementary.

Step-by-step explanation:

I made a small visual (mainly so I could visualize it but I figured it might help you too).

Since QRT is congruent to STR, QTR and SRT are also congruent.

Therefore, since STR is complementary to QTR, and STR is congruent to QRT, QTR must be complementary to QRT due to the transitive property.

The angles QRT and QTR are complementary (sum up to 90°)

What is an angle?

An angle is formed from the intersection of two lines. Types of angles are acute, obtuse and right angled.

In triangle QRT:

∠QRT + ∠QTR + ∠TQR = 180° (angle in a triangle)

90 + ∠QRT + ∠QTR = 180

∠QRT + ∠QTR = 90°

The angles QRT and QTR are complementary (sum up to 90°)
