Its simple ! A complementary angle is equal to 90 degrees . Also if the sum of two angles at a same point is equal to 90 degrees they are said to be complementary angles.
Yes.
180 degrees.
A supplementary angle can not be a complementary angle. The complementary angle has 2 angles equal 90... but a supplementary angle is X2 that much (108). * * * * * Nearly correct. 90 x 2 is 180, not 108!
A complementary angle is an angle that when added to another angle creates a 90o angle. A supplementary angle is an angle that when added to another angle creates a 180o angle.
equal to each other
Complementary angle to which angle?
1 plus 2 is equal to 3
An obtuse angle has no complementary angle.
180
Sure. It's quite possible for them to not be equal if they're complementary. In fact,the only angle that's equal to its complement is 45 degrees. No other one is.
