FAQ: What Is A Complementary Angle In Math?

What is a complementary angle example?

When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.

What is complementary and supplementary angle?

A complementary angle is an angle that adds up to 90 degrees. supplementary angles add up to 180 degrees. So a supplementary angle lies on a single, straight line, and a complementary angle is a right angle.

What is the complementary angle of 63?

Answer. So the complement of 63 ° is 27°.

What is straight angle?

: an angle whose sides lie in opposite directions from the vertex in the same straight line and which equals two right angles.

What are the 7 types of angles?

The 7 types of angles are: right angles, acute angles, obtuse angles, straight angles, reflex angles, full angles, and complementary angles.

Can an angle be both complementary and supplementary?

Yes, because the sum of two angles is 180, and if they are both 90 degrees, they add up to 180, making them supplementary, and of the same measure, making them congruent.

What is a requirement of complementary angles?

The measures of complementary angles must add up to 90°. The measures of complementary angles must add up to 180°.

Can complementary angles be more than 2?

Complementary angles are two angles whose measures add up to 90 degrees. Three or more angles are also not called complementary, even if their measures happen to add up to 90 degrees.
