Explore:  Compare the measures of , .

Plan:       To compare the angle measures use the properties and theorems of real numbers.

Solve:     Compare .

                Since is an exterior angle. By the exterior angle theorem the measure of is

                greater than the measure of either of its corresponding remote interior angles.

                So, .

                Compare .

                Again, by the exterior angle theorem the measure of is

                greater than the measure of either of its corresponding remote interior angles.

                So, .

Check:    is greater than the measures of . Thus, is the greastest measure.
