Sketch each angle below on your paper, and label each one with its measure in degrees.

1. Identify whether each angle is an acute, obtuse, or right angle.

   Hint (a):

   Recall that acute angles are angles that measure less than $90°$, obtuse angles measure more than $90°$, and right angles measure exactly $90°$.

2. Which angles could form a complementary pair?

   Hint (b):

   Complementary angles are two angles that add up to $90°$.
   For example, a $30°$ angle and a $60°$ angle are complementary because $30°+ 60° = 90°$.

3. Which angles could form a supplementary pair?

   Hint (c):

   Supplementary angles are angles that add up to $180°$.
   For example, $110°$ and $70°$ are supplementary angles because $110° + 70° = 180°$.
