science space and astronomy# How many degrees is a complementary angle?

Last Updated: 13th March, 2020

**90degrees**(a Right Angle). They don't have to be next to eachother, just so long as the total is

**90 degrees**. Examples:60° and 30° are complementary angles.

Consequently, what is the measure of complementary angle?

Straight lines **measure** 180°. That means thatthese two **angles** are supplementary. **Complementaryangles** form a right **angle** (L shape) and have a sum of 90degrees. Supplementary **angles** form a straight line and havea sum of 180 degrees.

One may also ask, can 3 angles be complementary? Three or more **angles** are also not called**complementary**, even if their measures happen to add up to 90degrees.

what is complementary angle and supplementary angle?

**Supplementary angles** are two **angles** whosesum is 180 degrees while **complementary angles** are two**angles** whose sum is 90 degrees. **Supplementary** and**complementary angles** do not have to be adjacent (sharing avertex and side, or next to), but they can be.

What is the complementary angle of 38 degrees?

**Complementary angles** are two **angles** thatequal 90 **degrees** when their measures are added together. Forexample, an **angle** of 15 **degrees** would have a**complementary angle** of 75 **degrees**.
