Parallelogram
A parallelogram is a quadrilateral (a polygon with four sides) that has two pairs of parallel sides
A parallelogram is a quadrilateral (a polygon with four sides) that has two pairs of parallel sides. In other words, the opposite sides of a parallelogram are equal in length and parallel to each other.
Properties of a Parallelogram:
1. Opposite sides are equal in length: The two pairs of opposite sides of a parallelogram are equal in length. This property is also known as the Converse of the Parallelogram Property.
2. Opposite angles are congruent: The opposite angles of a parallelogram are equal in measure (congruent). This property is known as the Consecutive Angles Property.
3. Consecutive angles are supplementary: The consecutive angles (angles that are adjacent and share a side) of a parallelogram are supplementary, meaning that their measures add up to 180 degrees.
4. Diagonals bisect each other: The diagonals of a parallelogram bisect each other, meaning that they intersect at their midpoints. This property is known as the Diagonal Property.
Formulas for a Parallelogram:
1. Area: The area of a parallelogram can be determined by multiplying the length of the base (one of the parallel sides) by the height (the perpendicular distance between the two parallel sides):
Area = base x height
2. Perimeter: The perimeter of a parallelogram is calculated by adding the lengths of all four sides:
Perimeter = 2a + 2b, where a and b are the lengths of the two pairs of parallel sides.
Examples of Parallelograms:
1. Rectangle: A rectangle is a special type of parallelogram where all angles are right angles (90 degrees). Opposite sides are equal in length.
2. Rhombus: A rhombus is also a special type of parallelogram where all four sides have equal length. Opposite angles are equal in measure.
3. Square: A square is a special type of parallelogram, rectangle, and rhombus where all angles are right angles and all sides are equal in length.
These are the basic properties and formulas related to parallelograms. It’s important to understand and apply these concepts when solving problems involving parallelograms.
