Calculation History


    1. Definition and Basic Properties:
      • A parallelogram is a four-sided figure (quadrilateral) in which opposite sides are parallel and equal in length.
      • The opposite angles in a parallelogram are also equal, and the adjacent angles are supplementary (sum up to 180 degrees).
    2. Key Features:
      • Sides: Opposite sides are parallel and of equal length.
      • Angles: Opposite angles are equal, and adjacent angles are supplementary.
      • Diagonals: Diagonals of a parallelogram bisect each other but are not necessarily equal.

    Mathematical Principles of Parallelograms

    1. Area Calculation:
      • The area of a parallelogram is given by the formula: Area=base×height
      • This formula is derived from the fact that the area of a parallelogram is equivalent to the area of a rectangle with the same base and height.
    2. Perimeter Calculation:
      • The perimeter of a parallelogram is the sum of the lengths of its four sides, calculated as: Perimeter=2×(length+width).
    3. Diagonals:
      • The diagonals of a parallelogram can be calculated using vector methods or by applying the Law of Cosines in trigonometry.
