# Angles 1 and 2 are complementary and congruent. What is the measure of angle 1?

Complimentary angles can also be referred to as corner angles since a corner angle is equal to 90 degrees as well.

## Answer: If 1and 2 are complementary and congruent, then the measure of angle 1 is equal to 90^{°} - angle 2.

Go through the explanation to understand in more depth.

**Explanation:**

Complimentary angles are the pair of angles whose sum is equal to 90 degrees.

Example: 27 degree and 63 degree, since 27 degrees + 63 degrees = 90 degrees.

Complimentary Angles V/S Supplementary Angles:

Supplementary angles are the pair of angles whose sum is 180 degrees.
