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.

Rectangle qrst is shown. angle qrt is congruent to angle str, and angle str is complementary to angle qtr.

Rectangle can be split into two triangles qtr and str.

We know every angle in a triangle is 90 degree.

In a triangle qtr,  ∠rqt is 90 degree. Also we know the sum of angles in a triangle is 180 degree.

So ∠rqt + ∠qtr + ∠qrt = 180 degree

90 + ∠qtr + ∠qrt = 180 (Subtract 90 on both sides)

∠qtr + ∠qrt = 90

Hence , ∠qtr and  ∠qrt are complementary angles.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
