Front

What is the relationship between the angles in a linear pair?

Back

They are supplementary, meaning they add up to 180 degrees.

CCSS.7.G.B.5

Front

What is the measure of the missing angle if one angle is 47 degrees and the other is 133 degrees?

Back

180 - (47 + 133) = 0 degrees (not possible, check angles)

Front

What is the measure of the missing angle if one angle is 50 degrees and the other is 50 degrees in a triangle?

Back

80 degrees (180 - (50 + 50) = 80)
