Define supplementary angles.

Supplementary angles are two angles whose measures add up to 180 degrees. In other words, when two angles are supplementary, they form a straight line and together create a right angle.

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

The sum of the measures of two supplementary angles is 180 degrees.

Give an example of a pair of supplementary angles.

One example of a pair of supplementary angles is an angle measuring 60 degrees and its supplementary angle, measuring 120 degrees, because when added together, they equal 180 degrees.

How can you determine if two given angles are supplementary?

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

If one angle measures 110 degrees, what is the measure of its supplementary angle?

The supplementary angle of an angle measuring 110 degrees would measure 70 degrees, as supplementary angles add up to 180 degrees.

Can two obtuse angles be supplementary? Explain.

No, two obtuse angles cannot be supplementary. Supplementary angles add up to 180 degrees, but each obtuse angle already measures more than 90 degrees, so if you were to add two obtuse angles together, the sum would exceed 180 degrees. Therefore, two obtuse angles cannot be supplementary.

Are all right angles supplementary to each other? Justify your answer.

Yes, all right angles are supplementary to each other. This is because the definition of supplementary angles is that the sum of their measures equals 180 degrees. Since a right angle measures 90 degrees, two right angles together will total 180 degrees, meeting the criteria for being supplementary. Therefore, any two right angles will always be supplementary to each other.

Can a pair of acute angles be supplementary? Explain.

No, a pair of acute angles cannot be supplementary because by definition, supplementary angles add up to 180 degrees. Since acute angles are less than 90 degrees, the sum of two acute angles will always be less than 180 degrees, making them unable to be supplementary.

If the measure of one angle is twice the measure of another angle, can they be supplementary? Why or why not?

No, if the measure of one angle is twice the measure of another angle, they cannot be supplementary. Supplementary angles add up to 180 degrees, so if one angle is twice the measure of another angle, it means the angles are not complementary. For example, if one angle is 60 degrees, the other angle would have to be 120 degrees for them to be supplementary, which would not make them twice the measure of each other.

How can you use the concept of supplementary angles to solve a geometry problem?

To solve a geometry problem using the concept of supplementary angles, you can identify two angles that add up to 180 degrees. If you have one angle measure, you can subtract it from 180 degrees to find the measure of the other angle. By knowing that supplementary angles form a linear pair and add up to a straight angle, you can use this relationship to find missing angle measures or solve for unknown variables in geometric figures.
