Question

In the diagram below, lines m and n are parallel.

The measures of two of the angles are known:

Match each angle with its measure.

Answer 1

< FBG = 132

< CDF = 132

< DFE = 107

< FDE = 48

< FED = 180

Answer 2

< FBG = 132
< CDF = 132 -- alternate interior angles are congruent
< DFE = since <BFE = 73, < DFE = 180 - 73 = 107
< FDE = 180 - 132 = 48
< FED = 180 - (107 + 48) = 180 - 155 = 25
