### Rectangle In the case of rectangle all interior angles are right angles (90°) and opposite sides are parallel and equal in length. The rectangle is also known as quadrilaterals. The diagonals of rectangle are congruent.

### Parallelogram In the case of parallelogram none of interior angles can not be right-angles(90°) and opposite sides are parallel and equal in length.

### Types of parallelogram

Rhombus: The parallelogram which is having all equal sides. Means a parallelogram having four congruent sides. There are shapes like diamond, rhomb or lozenge.

Rectangle: The parallelogram which is having all right angles and the diagonals are equal. Means a parallelogram having four congruent interior angles.

Square: The parallelogram having all equal sides and all angles equal to 90 degrees. The diagonals of a square are also equal. Means the parallelogram having four congruent sides and four congruent interior angles.
