The words such as complementary and supplementary are quite commonly used in the daily life but they have some different and useful meaning when it comes to the geometry. The terms are used to represent the pair of angles where if the sum of two angles results in 90 degrees then they are said to be complementary angles and if the sum is 180 degrees then they are said to be supplementary angles. The quiz here tries to give a complete knowledge of them by giving the child a good exposure to the different type of questions.

What are complementary and supplementary angles?

In geometry, angles are used to measure the amount of turn between two lines or segments. When two angles are put together, they can create different types of angle pairs. One type of angle pair is called complementary angles.

Complementary angles are two angles that add up to 90 degrees. This means that if you put the two angles together, they will form a right angle. A right angle is an angle that measures 90 degrees.

Here’s an example:

Imagine you have two angles that are drawn on a piece of paper. One angle measures 40 degrees and the other angle measures 50 degrees. If you put the two angles together, they will form a right angle because 40 degrees + 50 degrees = 90 degrees. This means that the two angles are complementary angles.

Another type of angle pair is called supplementary angles. Supplementary angles are two angles that add up to 180 degrees. This means that if you put the two angles together, they will form a straight angle. A straight angle is an angle that measures 180 degrees.

Here’s an example:

Imagine you have two angles that are drawn on a piece of paper. One angle measures 70 degrees and the other angle measures 110 degrees. If you put the two angles together, they will form a straight angle because 70 degrees + 110 degrees = 180 degrees. This means that the two angles are supplementary angles.

It’s important to remember that complementary angles and supplementary angles are different from each other. Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees.
