Complementary angles.

What are Complementary angles?

Two angles having a sum of 90^∘are said to be Complementary angles.

There are two types of complementary angles:

Two angles having a common arm, a common angle vertex, and the sum of their measure equal to 90^∘are known as Adjacent complementary angles.

Adjacent complementary angles ∠ABD and ∠DBC

Two angles having a sum of their measure 90^∘ but no common arm and no common angle vertex are known as Non-adjacent complementary angles.
