  • The two angles are said to be complementary angles if the sum of those angles is 90o
  • Acute angles are angles less than 90°
  • So two acute angles can be complementary to each other.
  • A right angle measures 90° whereas an obtuse angle measures more than 90° so they cannot be a part of complementary angles.
