## Parallelogram

### A parallelogram is a type of quadrilateral, which is a polygon with four sides

A parallelogram is a type of quadrilateral, which is a polygon with four sides. In a parallelogram, opposite sides are parallel and equal in length, which means they never intersect and have the same measurement. Also, opposite angles in a parallelogram are congruent, meaning they have the same measure. Each angle in a parallelogram measures 180 degrees, so the sum of all angles in a parallelogram is always 360 degrees.

Some properties of a parallelogram include:

1. Opposite sides are parallel: This means that if you extend the sides of a parallelogram, they will never intersect.

2. Opposite sides are equal in length: This means that the lengths of the two pairs of opposite sides of a parallelogram are the same.

3. Opposite angles are congruent: The measures of the two pairs of opposite angles in a parallelogram are equal.

4. Consecutive angles are supplementary: The sum of any two consecutive angles in a parallelogram is always 180 degrees.

There are different types of parallelograms, such as rectangles, squares, and rhombuses. Each of these subcategories has additional properties and characteristics.

To find the area of a parallelogram, you can use the formula: Area = base x height, where the base is any one of the sides, and the height is the perpendicular distance between the base and its opposite side.

In summary, a parallelogram is a four-sided polygon with opposite sides that are parallel and equal in length. It has various properties, such as congruent opposite angles and sides, and consecutive angles that add up to 180 degrees. The area of a parallelogram can be found by multiplying the base by the height.
