## How do you teach complementary and supplementary angles?

One way is to remember that C comes before S in the alphabet, so complementary angles are the smaller ones that add to 90 and supplementary are the larger ones that add to 180. Let’s look at a few examples involving supplementary angles. We know that supplementary angles always add up to 180 degrees.

## What are supplementary examples?

Examples of Supplementary Angles 120° + 60° = 180° 90° + 90° = 180° 140° + 40° = 180° 96° + 84° = 180°

How do you find complementary and supplementary?

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. 90 – 43 = 47° The complement of 43° is 47°.

What is the difference between complementary and complimentary?

Complimentary with an i is used when something is free or when you give someone a compliment. Complement with an e means something that completes something else as when two things go well together.

### How do you do complementary?

How to Find Complementary Angles? If the sum of two angles is 90 degrees, then we say that they are complementary. Thus, the complement of an angle is obtained by subtracting it from 90. For example, the complement of 40° is 90° – 40° = 50°.

### What are the real life examples of complementary angles?

For example, if a rectangular piece of bread is cut into two pieces along the diagonal, we get two right triangles shapes from them, with a pair of complementary angles. We can also take a wall clock, where when the minute hand is at 12 and the hour hand is at 3, which gives a complementary angle.

What are complementary angles quizzes?

Q. What are complementary angles? answer choices. Angles that add up to 180° Angles that add up to 90°

What is the complement of 34?

For example, if a question asks “What is the Complement of an angle that measures 34?” we would take 90 (because complementary means 90 angle) and subtract 34 from it to find its complement which is a 56 angle.

#### What is the complement of 25?

Answer and Explanation: If the complement of an angle is 25 degrees, then the measurement of the angle will be 65 degrees. To find the complement of an angle, we subtract the…
