Missy is constructing a fence that consists of parallel sides ab and ef. complete the proof to explain how she can show that mlakl = 116

substitution property

1. alemate interior angles theorem. 2. substitution property

1. definition of complementary angles 2 substitution property

1. definition of supplementary angles 2 transitive property

1. same side interior angles theorem: 2 transitive property

1, Definition of Supplementary Angles 2 Transitive Property

Explanation:

Analyzing the construction of a fence by Missy we can imagine that the shape of MLAKL would have two parallel sides such as ML and AK being joined by KL, therefore a side of the fence produced by LA would act as an intersecting line generating supplementary angles, that when defined should sum up to produce a 180° angle.  With the transitive property of geometry, we can assume that ML and AK would have the same value as AB and EF.
