Name the pair of complementary angles and pair of supplementary angles

Complementary angles are those angles whose sum is 90

Supplementary angles are those angles whose sum is 180

<QTS= 150

<RTS=60

<VWU= 30

Hence <QTS + <VWU = 150+30= 180 are supplementary angles

and <RTS + <VWU= 60+30 = 90 are complementary angles

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
