Yes. Anything two angles that add to 90 degrees is complementary. Anything two angles that add to 180 degrees is supplementary.

What are complementary angles always?

Complementary angles are angles that always add to 90° (ninety degrees). They are usually adjacent to each other, however in theory do not have to be. An example is: Angle "a" is 38°, and is situated next to, or adjacent to Angle "b" which is 52°. In this case, both angles (38 and 52) sum to ninety degrees, which means Angle a is complementary with, or to, Angle b. Another example is: Angle "a" is 56°, and is situated next to, or adjacent to Angle "b" which is 43°. In this case, both angles (56 and 43) do not sum to ninety degrees, which means Angle a is not complementary with, or to, Angle b. Complementary angles are studied in conjunction with supplementary angles (angles which sum to 180°) and angles at a point (angles which sum to 360°). Note: There does not have to be only two angles (however this is the minimum requirement, because a ninety degree angle can't have a complement of 0°). There can be three, five, ten, twenty, or whatever number of angles you wish (remember, you are not limited to there being ninety one degree angles because angles can have decimal points too, i.e. 56.32°). Hope this helped.


Can an obtuse angle be both complementary and supplementary?

No, an obtuse angle cannot be both complementary and supplementary because the measures of complementary angles add up to 90 degrees, while the measures of supplementary angles add up to 180 degrees. An obtuse angle has a measure greater than 90 degrees, so it can only be supplementary, not complementary.


Can one of two complementary angles be obtuse?

No, one of two complementary angles cannot be obtuse, because only two acute angles that add up to 90 degrees are complementary and that an obtuse angle on its own is greater than 90 degrees.


Are alternate interior angles complementary?

Not NecessarilyAlternate interior angles are congruent, or equal. They have the same angle measure, while complementary means they add up to 90 degrees. Therefore, the only time alternate interior angles are complementary is when they are exactly 45 degrees.


What is the complement of a 124 degree angle?

Complementary angles only add up to 90 degrees but if you mean its supplementary angle then it is 56 degrees because they both add up to 180 degrees which are supplementary angles.


Can a angle be equal if it is complementary?

Only if it's 45 degrees. A complimentary is an angle whose compliment and itself when added together, equal 90 degrees. So, the only occasion where they could be equal is when both are 45 degrees, because 45+45= 90.


Can two angles not be equal if they are complementary?

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.


How can an angle have the same measure of its complement?

Complementary angles are 2 angles adding up to 90 degrees, so the only measurement complementary angles could have that would be matching would be 45 degrees, which is 90 divided by 2. :D


In geometry does every angle have a compliment?

No. Complementary angles add up to 90 degrees, so only those that measure less than or equal to 90 degrees can have a complEment.


How do you write the biconditional for If two angles are complementary then their sum is 90 degrees?

Two angles are complementary if and only if their sum is 90 degrees.


What is the opposite of a acute angle?

No such thing as opposite of acute angle. An ACUTE angle is an angle of less than 90 degrees. A RIGHT angle is an angle of 90 degrees only. An OBTUSE angle is an angle between 90 degrees and 180 dehrees. An angle of 180 degrees is a straight line. A REFLEX angle is an angle between 180 degrees and 360 degrees.


What are the 5 classification of the angles?

Angles can be complementary, supplementary, alternate, corresponding, perpendicular ..... etc but there are only 4 main angles which are as follows:- Acute angle is greater than 0 but less than 90 degree Right angle is 90 degrees Obtuse angle is greater than 90 but less than 180 degrees Reflex angle is greater than 180 but less than 360 degrees which is a complete revolution
