I’m late but that week we learned about rectangles. Rectangles are parallelograms with 4 right angles. It has two sets of parallel sides that are congruent. Consecutive angles are supplementary, diagonals bisect each other. If a parallelogram is a rectangle, then it’s diagonals are congruent. If the diagonals Of a parallelogram are congruent, then the parallelogram is a rectangle.
