# What is an example of a supplementary angle?

## What is an example of a supplementary angle?

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°. Hence, any two angles can be supplementary, if their sum equal to 180°.

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. Angles measuring 1 degree and 89 degrees.

What are complementary angles 5 examples?

Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don’t have to be next to each other, just so long as the total is 90 degrees. Examples: 5° and 85° are complementary angles.

### How do I find the complementary and supplementary 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 pairs of angles are supplementary?

Supplementary angles are two angles whose measures add up to 180° . The two angles of a linear pair , like ∠1 and ∠2 in the figure below, are always supplementary. But, two angles need not be adjacent to be supplementary. In the next figure, ∠3 and ∠4 are supplementary, because their measures add to 180° .

What is another name of supplementary angles?

And so are supplementary angles, a pair of two angles forming a straight angle (180 degrees) when they are put together. These two angles are certainly called supplements of each other.

## What is difference between complementary and supplementary?

“Complementary” means “completing or going together well with” something else. “Supplementary” means “adding to” something else. “Complementary” implies a stronger relationship between two things, whereas “supplementary” just means that one thing is additional or auxiliary to another.

What is the sum of the measures of supplementary angles?

180 degrees
Consider two supplementary angles: A and another angle. A and ( Another Angle ) Since they are supplementary, they add up to 180 degrees. A + ( Another Angle ) = 180 Notice that we call angle A by its name: “A”.

Can supplementary angles be complementary?

Two concepts that are related but not the same are supplementary angles and complementary angles. The difference is their sum. Supplementary angles are two angles whose measures sum to a 180 degrees and complementary are the sum have to add up to 90 degrees. The same is true for complementary angles.

### Which pair of angles are supplementary?

Can 3 angles be supplementary?

No, three angles can never be supplementary even though their sum is 180 degrees.

Which pair of angles is not supplementary?

Example : 1) 60° and 120° are supplementary angles. 2) 135° and 45° are supplementary angles. 3) 50° and 140° are not supplementary angles because their sum is not equal to 180 degree.

## What are some examples of complementary angles?

Complementary Angles: Two angles are said to be complementary if the sum of their measures is 90°, and each angle is said to be complement of each other. For example, (45°, 45°), (10°, 80°), (20°, 70°), (30°, 60°).

What are real life example of supplementary angles?

140° and 40°

• 120° and 60°
• 30° and 150°
• 90° and 90° etc.
• What angles are supplementary angles?

Supplementary Angles. Two Angles are Supplementary when they add up to 180 degrees. These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°: Notice that together they make a straight angle.

### How do you find the supplementary angles?

Supplementary Angles. Two angles are supplementary if the sum of their angles equals 180 o. If one angle is known, its supplementary angle can be found by subtracting the measure of its angle from 180 o.
