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.
No, not all congruent angles are 45 degrees. They only are in complementary congruent angles.
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.
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
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.
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.
Two angles are complementary if and only if their sum is 90 degrees.
Yes. Anything two angles that add to 90 degrees is complementary. Anything two angles that add to 180 degrees is supplementary.
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.
No, not all congruent angles are 45 degrees. They only are in complementary congruent angles.

It is an impossible quadrilateral since its angles would not sum to 360 degrees but only 180 degrees.
No, complementary angles need to ADD and EQUAL 90 degrees. Supplementary angles need to ADD/EQUAL 180 degrees. They do not necessarily need to be adjacent to each other, they only have to add up... Complementary = 90, Supplementary = 180
Only when they are supplementary angles
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
No only two angles can be complementary
No. Only the sum of the measures of the angles of a triangle equal to 180 degrees; in the case of a quadrilateral it amounts to 360 degrees.
