where are angles whose sum 180° are we
Answer (1)
A pair of angles whose sum are 180° is called supplementary angles. They can be adjacent, meaning they share a vertex and a side, but they don't have to be. Examples of supplementary angles:Angle A = 100°, Angle B = 80°Angle A = 120°, Angle B = 60Angle A = 160°, Angle B = 20°The sum of each example is 180° which means they qualify to be a supplementary angle.
