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 triangle have two complementary interior angles?
No. A triangle with two complementary interior angles will always result into right triangle. The sum of the complementary angles will always be 90 degrees and the other one will be 90 too.
Are congruent angles always 45º?
No, not all congruent angles are 45 degrees. They only are in complementary congruent angles.
Are adjacent angles sometimes always or never complementary?
Sometimes, because they both have two angles.
Are vertical angles complementary?
noe not always but maybee sumtimes it depends......:)
The opposite angles of a quadrilateral in a circumscribed circle are always complementary?
false
Are complementary angles always adjacent?
Are complementary angles alwys adjacent?
Can an obtuse triangle have two complementary interior angles?
No. A triangle with two complementary interior angles will always result into right triangle. The sum of the complementary angles will always be 90 degrees and the other one will be 90 too.
Is two acute angles are always complementary?
No
Are vertical angles always complementary?
Vertical angles are not always complementary. In some cases, they will congruent and supplementary which makes them add up to 180 degrees.
How do you find complementary and supplementary angles?
Complementary angles are found by subtracting a random angle from 90 degrees for complementary always and 180 for supplementary always
Complimentary angles are always what angles?
Complementary angles are angle that have degrees that add to 90 degrees.
Are congruent angles always 45º?
No, not all congruent angles are 45 degrees. They only are in complementary congruent angles.
Are adjacent angles sometimes always or never complementary?
Sometimes, because they both have two angles.

The opposite angles of a quadrilateral in a circumscribed circle are always complementary?
false
Do two complementary angles always form a linear pair?
No, angles that form a linear pair are supplementary.
Do two congruent angles that are complementary both measure 45 degrees?
always
