Sketch each angle below on your paper, and label each one with its measure in degrees. Homework Help ✎
Identify whether each angle is an acute, obtuse, or right angle.
Which angles could form a complementary pair?
Which angles could form a supplementary pair?
Recall that acute angles are angles that measure less than 90°, obtuse angles measure more than 90°, and right angles measure exactly 90°.
Complementary angles are two angles that add up to 90°.
For example, a 30° angle and a 60° angle are complementary because 30°+ 60° = 90°.
Supplementary angles are angles that add up to 180°.
For example, 110° and 70° are supplementary angles because 110° + 70° = 180°.
