Question

rectangle qrst is shown. angle qrt is congruent to angle str, and angle str is complementary to angle qtr. which statement is true about angles qrt and qtr? they are congruent. they are complementary. they are supplementary. they are right angles.

Explanation:

1. Dado que \( \angle QRT \cong \angle STR \) y \( \angle STR \) es complementario a \( \angle QTR \) (es decir, \( \angle STR + \angle QTR = 90^\circ \)).
2. Sustituyendo \( \angle STR \) por \( \angle QRT \) (debido a la congruencia), tenemos \( \angle QRT + \angle QTR = 90^\circ \).
3. Por definición, dos ángulos que suman \( 90^\circ \) son complementarios.

Answer:

They are complementary.
