Supplementary angles has the sum of the two angles that equal 180 degrees, while complementary angles have the sum of 90 degrees between two angles.

Complementary angles sum to 90º, like 30º + 60º. Supplementary angles sum to 180º, like 45º and 135º.

**SUPPLEMENTARY ANGLES = the sum of the two angles are
180**

**WHILE**

**COMPLEMENTARY ANGLES=** **the sum of the two angles are

### What are supplementary and complementary angles?

The sum of two complementary angles is 90.
E.g. 30 degrees and 60 degrees are each others complementary
angles.
The sum of two supplementary angles is 180.
E.g. 105 and 75 are each others supplementary angles.
Supplementary angles are those whose angles add up to 180 degrees.
Complementary angles are those whose angles add up to 90
degrees.
