Special Parallelograms Exit

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

A rectangle is a parallelogram with four right angles. Opposite sides are equal in length, and the diagonals are congruent.

In a rectangle, if you know the lengths of two sides (a and b), the length of the diagonal (c) can be found using the formula: c = √(a² + b²).

A rhombus is a type of parallelogram where all four sides are of equal length.

The diagonals of a rhombus are perpendicular to each other and bisect each other at right angles.

In a rhombus, opposite angles are equal, and adjacent angles are supplementary (add up to 180 degrees).

In a rectangle, opposite sides are equal, and all angles are right angles (90 degrees).

If the diagonals of a parallelogram bisect each other, it confirms that the figure is a parallelogram.

The area of a parallelogram is calculated using the formula: Area = base × height.

A quadrilateral is a parallelogram if one pair of opposite sides is both parallel and equal in length.
