The question does not really make sense. Once might ask, "Are consecutive angles in a parallelogram complementary?" in which case the answer is no. Complementary angles are angles which add up to 90 degrees. Consecutive angles are angles next to each other (or follow each other). In a parallelogram, consecutive angles are supplementary (add to 180 degrees). In a parallelogram, opposite angles are equal. You could have a parallelogram where two angles are 45 degree (and thus complementary) and then the other two angles would be 135 degrees.

45 degree and a 90 degree angles
A quadrilateral that could have a 45-degree vertex angle is a kite. In a kite, the two pairs of adjacent sides are congruent, and one pair of opposite angles is congruent. Therefore, if one of the angles is 45 degrees, the opposite angle would also be 45 degrees. This makes a kite one of the quadrilaterals that could have a 45-degree vertex angle.
A triangle with two 45 degree angles would have one 90 degree angle.It would be a right triangle.Further Information:-It is an isosceles right angle triangle
No because the 4 interior angles must add up to 360 degrees
No it cannot, because the interior angles of a parallelogram ... or of anyfour-sided figure for that matter ... must add up to 360 degrees.
No because the total sum of interior angles of a parallelogram are 360 degrees.

A triangle with two 45 degree angles must be a right triangle.
No, because it doesn't equal 360 degrees
it is 45 degree
acute 45 degree angles
No it cannot, because the four angles must sum to 360 degrees.
45 degree and a 90 degree angles
They have one 90 degree angle and two 45 degree angles
Yes- both will be 45-degree angles.
