Complementary and Supplementary AnglesDate: 10/24/1999 at 12:44:55 From: S.M.ABDULLAH AURANGZEB Subject: Complementary and Supplementary Angles Complementary angles: I have defined complementary as "if the sums of two angles is 90 degrees, or a right angle, then they are called complementary angles." Is this right? Supplementary angle: "if the sum of two angles is 180 degrees, or a straight angle, they are called supplementary angles." Is this right? Date: 10/24/1999 at 14:11:14 From: Doctor White Subject: Re: Complementary and Supplementary Angles S.M. - Your definitions are correct. Complementary angles are two angles whose sum equals 90 degrees. Example: 30 degrees and 60 degrees are complementary (30 + 60 = 90) Supplementary angles are two angles whose sum equals 180 degrees. Example: 125 degrees and 55 degrees are supplementary (125 + 55 = 180) - Doctor White, The Math Forum http://mathforum.org/dr.math/ |
