A rectangle which is technically a parallelogram
A paralleogram having 4 congruent sides means it would be a rhombus or a square if it had right angles.

No. In a parallelogram, opposite angles are congruent.
There are no right angles in a parallelogram. A parallelogram only has right angles if it is a rectangle, in which case it has exactly four.
A square and a rectangle both fit the description
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.
A parallelogram does not necessarily intersect at right angles. In a parallelogram, opposite angles are equal, and adjacent angles are supplementary, which means they can vary in measure. However, if the parallelogram is specifically a rectangle or a square, then it does intersect at right angles. Otherwise, a general parallelogram typically does not have right angles.
Opposite angles of a parallelogram are equal.
Yes, opposite angles of a parallelogram are congruent.
Except for rectangles, no parallelogram has right angles.
a parallelogram has two pairs of equal angles
Adjacent angles in a parallelogram are supplementary.
