FAQ: What Is Complementary Angle In Math?

What is complementary angle with example?

Complementary angles are pair angles with the sum of 90 degrees. Common examples of complementary angles are: Two angles measuring 45 degrees each. Angles measuring 30 and 60 degrees.

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 the complementary angle of 120?

usually when you talk about complementary angles, the angles are assumed to be positive angles less than 90 degrees. in order for those angles to be complementary, their sum must be equal to 90 degrees. since a 120 degrees angle is greater than 90 degrees, then complementary is assumed not to apply.

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.

How many types of angle are there?

The different types of angles based on their measurements are: Acute Angle – An angle less than 90 degrees. Right Angle – An angle that is exactly 90 degrees. Summary.

Angle Type Angle measure
Obtuse angle Greater than 90°, less than 180°
Straight angle 180°
Reflex angle Greater than 180°, less than 360°

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.

Which angle is supplementary to Doc?

1. Consider angle ∠COB: m∠ DOC +m∠COB=m∠DOB=180°. This means that angles ∠ DOC and ∠COB are supplementary.

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.

Does a straight angle have a compliment?

unless we consider negative angles to be fair game Complements add to 90 degreesa straight angle is already 180

What is the complement of 20 degrees?

So if you have an angle that is 20 degrees, then the complement angle measures 70 degrees.

What is the complementary angle of 65 degree?

Angles of measure 25° and 65 ° are complementary angles. The angle of 25° is the complement of the angle of 65 ° and the angle of 65 ° is the complement of the angle of 25°.
