The perimeter of a parallelogram is the length of its outline and hence it is equal to the sum of all its sides. Applying the parallelogram properties, we know that the opposite angles are equal.

We also know that the adjacent angles of a parallelogram are supplementary. In geometry, a quadrilateral is called a parallelogram. A parallelogram has its opposite sides parallel and equal in length. Few examples of a parallelogram are rhombus, rectangle, and square.

All parallelograms are quadrilaterals but all quadrilaterals are not necessarily parallelograms. For example, a trapezoid is a quadrilateral, but not a parallelogram. For a quadrilateral to be a parallelogram, all the opposite sides must be parallel and equal to each other.

A parallelogram is a special kind of quadrilateral in which the opposite sides are parallel and equal. Yes, a rhombus is a parallelogram in which the opposite sides are parallel and the opposite angles are congruent. Apart from this, all the sides of a rhombus are equal and the diagonals bisect each other at right angles.

No, a trapezoid is not a parallelogram, since all opposite sides of the trapezoid are not parallel to each other. A trapezoid has only one pair of opposite sides parallel to each other. Also, a trapezoid doesn't have opposite sides equal to each other. Hence, it is a quadrilateral but not a parallelogram. Yes, a rectangle is a parallelogram in which the opposite sides are parallel and equal. Apart from this, all the angles of a rectangle are congruent and it has equal diagonals that bisect each other.
