 # What Is The Sum Of The Complementary Angles?

## What are the 5 types of angle?

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.Obtuse Angle – An angle more than 90 degrees and less than 180 degrees.Straight Angle – An angle that is exactly 180 degrees.More items….

## What do vertical angles look like?

The angles opposite each other when two lines cross. They are always equal. In this example a° and b° are vertical angles. … They are also called vertically opposite angles.

## How do you solve supplementary and complementary angles?

If we know that a set of angles form one of these special relationships, we can determine the measure of the other angle. To determine the supplement, subtract the given angle from 180. 180 – 43 = 137° The supplement of 43° is 137°. To determine the complement, subtract the given angle from 90.

## What is a supplementary angle example?

Supplementary angles are those angles that measure up to 180 degrees. For example, angle 130° and angle 50° are supplementary because on adding 130° and 50° we get 180°. Similarly, complementary angles add up to 90 degrees. … Hence, any two angles can be supplementary, if their sum equal to 180°.

## What are the six types of angles?

Types of AnglesAcute Angle: An angle whose measure is less than 90° is called an acute angle.Right Angle: An angle whose measure is 90° is called right angle.Obtuse Angle: An angle whose measure is greater than 90° but less than 180° is called an obtuse angle. … Straight Angle: … Reflex Angle: … Zero Angle:

## How do you do complementary angles?

If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary. If you know one acute angle, you can calculate its complementary angle by subtracting 90 and the angle.

## Can two angles be supplementary if both of them are?

∴Sum of two acute angles cannot make a supplementary angle. As we know that obtuse angle is always greater than 900. So, the sum of two obtuse angles always makes greater than 1800. … So, the sum of two right angles is always equal to 1800.

## What is the sum of the measure of two supplementary angles?

Consider two supplementary angles: A and another angle. A and ( Another Angle ) Since they are supplementary, they add up to 180 degrees.

## What is the complementary angle?

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 the complementary angle of 20?

Example, 20° and 70° are complementary angles, because 20° + 70° = 90°. Clearly, 20° is the complement of 70° and 70° is the complement of 20°.

## Can 3 angles be complementary?

Three angles or more angles whose sum is equal to 90 degrees cannot also be called complementary angles. Complementary angles always have positive measures. it is composed of two acute angles measuring less than 90 degrees.
