Supplementary Angles

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

If one angle measures 90 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle measures 90 degrees.

Front

What is the measure of Angle A if it is supplementary to an angle measuring 152 degrees?

Back

Angle A measures 28 degrees (180 - 152 = 28).

Front

What is the measure of Angle A if it is supplementary to an angle measuring 88 degrees?

Back

Angle A measures 92 degrees (180 - 88 = 92).

Front

What is the measure of Angle A if it is supplementary to an angle measuring 120 degrees?

Back

Angle A measures 60 degrees (180 - 120 = 60).

Front

What is the measure of Angle A if it is supplementary to an angle measuring 119 degrees?

Back

Angle A measures 61 degrees (180 - 119 = 61).

Front

What is the measure of Angle A if it is supplementary to an angle measuring 23 degrees?

Back

Angle A measures 157 degrees (180 - 23 = 157).

Front

How do you find the measure of a supplementary angle?

Back

To find the measure of a supplementary angle, subtract the measure of the given angle from 180 degrees.

Front

If two angles are supplementary, what is their total measure?

Back

The total measure of two supplementary angles is always 180 degrees.

Front

Can two angles both be obtuse and still be supplementary?

Back

No, two obtuse angles cannot be supplementary because their measures would exceed 180 degrees.
