Parallelogram

A parallelogram is a type of quadrilateral, a four-sided polygon

A parallelogram is a type of quadrilateral, a four-sided polygon. It is characterized by its opposite sides being parallel and equal in length. This means that if you extend the sides of a parallelogram, they never intersect. Additionally, the opposite angles of a parallelogram are also equal.

Properties of a parallelogram:
1. Opposite sides are parallel: This means that the two pairs of opposite sides in a parallelogram never intersect and are always parallel to each other.
2. Opposite sides are equal in length: The lengths of the opposite sides of a parallelogram are equal.
3. Opposite angles are equal: The measures of the opposite angles in a parallelogram are equal. Each pair of opposite angles is congruent.
4. Consecutive angles are supplementary: This means that the sum of any two consecutive angles in a parallelogram is always 180 degrees.
5. Diagonals bisect each other: The diagonals of a parallelogram intersect at their midpoints. This means that each diagonal divides the parallelogram into two congruent triangles.

Formulas and calculations related to a parallelogram:
1. Area of a parallelogram: The area of a parallelogram can be calculated by multiplying the base (length of one of the sides) by the height (the perpendicular distance between the base and the opposite side).
Area = base * height

2. Perimeter of a parallelogram: The perimeter of a parallelogram is the sum of all its four sides, which can be calculated by adding the lengths of all the four sides.
Perimeter = side1 + side2 + side3 + side4

Examples of parallelograms in real life include doors, certain types of buildings, tables, and rectangular fields.
