The interior and exterior angle at each point/vertex add up to 180° , which means that they are supplementary angles. 127° + 75° = 202° final answer since the sum of the two interior angles is 202°, therefore the lines are not parallel. They are exterior angles meaning they are outside of the two parallel lines opposite to interior angles which are two parallel lines. The exterior angles of a polygon are angles outside of the shape formed between any side of the polygon and a line extended from the side next to it. The exterior angle is the angle between any side of a shape, when we add up the interior angle and exterior angle we get a straight line 180°. Same Side Exterior Angles cloudshareinfo.
