Supplementary Angles- (no algebra)

Front

What are supplementary angles?

Back

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

Front

If one angle measures 104 degrees, what is the measure of its supplementary angle?

Back

76 degrees (180 - 104 = 76).

Front

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

Back

The sum is always 180 degrees.

Front

If angle A is 78 degrees, what is the measure of its supplementary angle?

Back

102 degrees (180 - 78 = 102).

Front

Are 78 degrees and 102 degrees supplementary?

Back

Yes, because 78 + 102 = 180 degrees.

Front

What is the measure of angle B if angle A is 141 degrees?

Back

Angle B is 39 degrees (180 - 141 = 39).

Front

If angle 1 is 78 degrees and angle 2 is 102 degrees, what type of angles are they?

Back

They are supplementary angles.

Front

What is the measure of the missing angle if one angle is 156 degrees?

Back

The missing angle is 24 degrees (180 - 156 = 24).

Front

If two angles are supplementary, what can you say about their measures?

Back

Their measures add up to 180 degrees.

Front

What is the relationship between complementary and supplementary angles?

Back

Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees.
