What are complementary angles?

Complementary angles are a pair of angles that add up to 90 degrees. When two angles are complementary, one angle is the complement of the other, meaning they combine to form a right angle.

How are complementary angles related to each other?

Complementary angles are two angles that add up to 90 degrees. In other words, when placed together, complementary angles form a right angle. This relationship means that if you know the measure of one angle, you can find the measure of its complementary angle by subtracting it from 90 degrees.

How can you find the measure of a complementary angle?

To find the measure of a complementary angle, subtract the measure of the given angle from 90 degrees. Complementary angles add up to 90 degrees, so by subtracting the measure of the given angle from 90 degrees, you can determine the measure of its complementary angle.

Can two obtuse angles be complementary? Why or why not?

No, two obtuse angles cannot be complementary because complementary angles add up to 90 degrees, but obtuse angles are already greater than 90 degrees. Therefore, it is not possible for two obtuse angles to add up to 90 degrees and be considered complementary.

If one angle is acute, what can we say about its complementary angle?

If one angle is acute, its complementary angle must be obtuse as the sum of an acute angle and an obtuse angle always equals 90 degrees.

What is the sum of the measures of two complementary angles?

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

Can two right angles be considered complementary angles? Explain.

No, two right angles cannot be considered complementary angles. Complementary angles are two angles that add up to 90 degrees, while a right angle measures exactly 90 degrees. Since two right angles already add up to 180 degrees, they do not meet the criteria to be complementary angles as they exceed the 90-degree requirement.

Can two angles with measures less than 90 degrees be complementary? Why or why not?

No, two angles with measures less than 90 degrees cannot be complementary because complementary angles add up to 90 degrees. Since both angles are less than 90 degrees, their sum will also be less than 90 degrees, which means they cannot fulfill the definition of complementary angles.

If one angle is 30 degrees, what is the measure of its complementary angle?

The measure of the complementary angle would be 60 degrees because complementary angles add up to 90 degrees, and 90 - 30 = 60.

Can two angles with measures greater than 90 degrees be complementary? Why or why not?

No, two angles with measures greater than 90 degrees cannot be complementary. Complementary angles are two angles that add up to 90 degrees. Since angles greater than 90 degrees already exceed 90 degrees individually, they cannot be combined to equal 90 degrees and therefore cannot be considered complementary.
