Then it's consecutive angles are supplementary.
Yes.
a rectangle has four right angles and opposite sides are all the same length This means that a parallelogram is not always a rectangle, but a rectangle is always a parallelogram, by definition.
An equilateral quadrilateral which would include a square.
Except for rectangles, no parallelogram has right angles.
Not unless the parallelogram is a rectangle. In every parallelogram, consecutive angles are supplementary.
The Parallelogram Consecutive Angles Conjecture states that the consecutive angles in a parallelogram are supplementary. This means that the sum of two adjacent angles in a parallelogram is always 180 degrees. This property follows from the fact that opposite angles in a parallelogram are congruent.
Consecutive angles of a parallelogram are supplementary.
Consecutive angles in a parallelogram are supplementary.
Then it's consecutive angles are supplementary.
Supplementary.
supplementary
No.
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.

Consecutive angles in a parallelogram will not be complementary. Complementary would mean the angles would add up to 90 degrees. Consecutive angles add up to 180 degrees, meaning they are supplementary.
