1. In figure 2.18, y = 108° and x = 71° Are the lines m and n parallel ? Justify ? Solution: Given y = 108˚ x = 71˚ If lines m and n are parallel, then angles x and y are supplementary. [Interior angles test] Here x+y = 71+108 = 179 ≠ 180. So angles x and y are not supplementary. Angles x and y fail the interior angle test for parallel lines.
