Parallelograms have consecutive angles that are supplementary and add up to 180 degrees
No. All linear pair angles are supplementary, but supplementary angles do not have to be a linear pair.
In all parallelograms, opposite angles are equal and the 4 interior angles add up to 360 degrees. In someparallelograms, all of the angles are 90 degrees. These parallelograms are rectangles.
No, because to have a rectangle, you need to have four right angles, and parallelograms dont have to have right angles. However, all rectangles are parallelograms.
All rectangles have 90 degree angles and with parallelograms that does not always have to be the case. But no matter what in order for a parallelogram to be a rectangle the angles have to all be 90 degrees.Rectangles are special cases of parallelograms. They have all the properties of parallelograms, and in addition, all their internal angles are right-angles - 90° angles.
Parallelograms have consecutive angles that are supplementary and add up to 180 degrees
If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Opposite angles are congruent. Opposite sides are congruent. Consecutive angles are supplementary.
True
Yes. Two angles are suplementary if their sum is 180 degrees. All interior angles in a rectangle are 90 degrees, so any pair of these angles is supplementary.
it’s true
opposite angles of all parallelograms are always equal.

All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.

All supplementary angles do not form a linear pair. The opposite angles of any quadrilateral inscribed in a circle (a cyclic quadrilateral) are supplementary but they are not a linear pair. However, all linear pair are supplementary.
