Understanding Parallelograms

What is a Parallelogram?

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

  • Opposite sides are equal and parallel
  • Opposite angles are equal
  • Consecutive angles are supplementary
  • Diagonals bisect each other
  • Area can be calculated using base and height
  • Special cases include rectangles, rhombuses, and squares

Key Formulas

Area:

A = base × height

Perimeter:

P = 2(base + side)

Diagonal:

d = √(base² + height²)

Angle Relationships:

Angle A + Angle B = 180°
