Lesson Summary. Supplementary angles are any two angles whose measures sum to 180 degrees. Supplementary angle pairs will either be two right angles (both 90 degrees) or be one acute angle and one obtuse angle. If two angles are both supplementary to the same angle, then the two angles are of equal measure.
Supplementary angles has the sum of the two angles that equal 180 degrees, while complementary angles have the sum of 90 degrees between two angles. Complementary angles s â¦ um to 90Âº, like 30Âº + 60Âº. Supplementary angles sum to 180Âº, like 45Âº and 135Âº.he sum of complementary angles is 90Â°. The sum of supplementary angles is 180Â°. EXAMPLE: 27Â° is the complementary angle to 63Â° and the supplementary angle to 153Â°. 3 people found this useful. Edit. Share to: David Scott. 13,977 Contributions. Texas A&M Electrical Eng.
