Complementary angles are two angles with a sum of 90Âº. Supplementary angles are two angles with a sum of 180Âº. Vertical angles are two angles whose sides form two pairs of opposite rays. We can think of these as opposite angles formed by an X. The Lesson:
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.
