What are supplementary angles?

Supplementary angles are two angles that add up to 180 degrees when combined. In other words, if you have two angles that are supplementary, their measures will total to a straight line.

How can you determine if two angles are supplementary?

Two angles are supplementary if the sum of their measures is equal to 180 degrees. To determine if two angles are supplementary, simply add the measurements of the two angles together. If the sum equals 180 degrees, then the angles are supplementary.

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

The sum of the measures of two supplementary angles is always 180 degrees. When two angles are supplementary, it means that they add up to form a straight line.

Can two acute angles be supplementary?

No, two acute angles cannot be supplementary because supplementary angles are a pair of angles that add up to 180 degrees, making them either a straight angle or a linear pair of angles. Since acute angles are angles that measure less than 90 degrees, they cannot add up to 180 degrees and therefore cannot be supplementary.

Can two obtuse angles be supplementary?

No, two obtuse angles cannot be supplementary because in order for angles to be supplementary, the sum of their measures must be 180 degrees. Since an obtuse angle measures more than 90 degrees, the sum of two obtuse angles would be more than 180 degrees, making them unable to be supplementary.

How can you find the measure of one angle if you know it is supplementary to another angle?

To find the measure of one angle that is supplementary to another angle, you would subtract the measure of the known angle from 180 degrees. Supplementary angles add up to 180 degrees, so by subtracting the measure of the known angle from 180, you can calculate the measure of the other angle that is supplementary to it.

Are supplementary angles always adjacent?

No, supplementary angles are not always adjacent. Two angles are supplementary if the sum of their measures is 180 degrees. Adjacent angles are angles that share a common vertex and side but do not overlap. While supplementary angles can be adjacent, they can also be non-adjacent and located anywhere in relation to each other.

Are supplementary angles congruent angles?

No, supplementary angles are angles that add up to 180 degrees, while congruent angles are angles that have the same measure. Supplementary angles do not have to be congruent, as long as they add up to 180 degrees.

Can a straight angle be supplementary to itself?

No, a straight angle is already equal to 180 degrees, so it cannot be supplementary to itself as supplementary angles add up to 180 degrees.

What is the algebraic relationship between the measures of two supplementary angles?

The algebraic relationship between the measures of two supplementary angles is that their measures add up to 180 degrees. So if one angle is x degrees, then the other supplementary angle would be 180 - x degrees.
