Define complementary angles.

Complementary angles are two angles whose measures add up to 90 degrees. In other words, when the angles are placed side by side, they form a right angle.

How can you determine if two angles are complementary?

Two angles are complementary if the sum of their measures is equal to 90 degrees. To determine if two angles are complementary, simply add their measures together. If the sum is 90 degrees, then the angles are complementary.

What is the sum of the measures of complementary angles?

The sum of the measures of complementary angles is always 90 degrees.

Can complementary angles be adjacent?

Yes, complementary angles can be adjacent. Complementary angles are two angles that add up to 90 degrees, and adjacent angles are angles that share a common side and a common vertex but do not overlap. So, it is possible for two complementary angles to be adjacent if they share a common side and vertex and their measures add up to 90 degrees.

Can complementary angles be obtuse?

No, complementary angles by definition add up to 90 degrees. Therefore, complementary angles cannot be obtuse since an obtuse angle is greater than 90 degrees and would not be able to add up to 90 degrees with another angle.

Give an example of two angles that are complementary.

An example of two complementary angles is an angle measuring 30 degrees and its complement measuring 60 degrees. These two angles add up to 90 degrees, which is the definition of complementary angles.

How can you find the measure of one angle if you are given that it is complementary to another angle with a known measure?

To find the measure of one angle that is complementary to another angle with a known measure, you would subtract the known measure from 90 degrees. Complementary angles add up to 90 degrees, so by subtracting the known measure from 90 degrees, you can find the measure of the other angle.

Is it possible for three angles to all be complementary to each other?

No, it is not possible for three angles to all be complementary to each other. Complementary angles are two angles that add up to 90 degrees, so if three angles were all complementary to each other, their sum would exceed 90 degrees, which is not possible.

Are complementary angles always adjacent angles?

No, complementary angles are angles whose measures add up to 90 degrees, regardless of whether they are adjacent or not. Adjacent angles are angles that share a common vertex and side but do not have to add up to 90 degrees.

Can a right angle be considered complementary to any other angle?

No, a right angle cannot be considered complementary to any other angle. Complementary angles add up to 90 degrees, and a right angle itself measures exactly 90 degrees. Since a right angle already equals the sum of two complementary angles, it cannot be complementary to any other angle.
