    Quadrilaterals

    Definition

    • A quadrilateral is a polygon with four sides and four vertices.

    Types of Quadrilaterals

    • A rectangle is a quadrilateral with all angles being right angles (90 degrees) and opposite sides of equal length.
    • A square is a quadrilateral with all angles being right angles (90 degrees) and all sides of equal length.
    • A rhombus is a quadrilateral with all sides of equal length, but not necessarily right angles.
    • A trapezoid (or trapezium) is a quadrilateral with at least two pairs of opposite sides that are not equal in length.
    • A kite is a quadrilateral with two pairs of adjacent sides of equal length, and one pair of opposite angles that are equal.
    • An irregular quadrilateral is a quadrilateral that does not fit into any of the above categories.

    Properties of Quadrilaterals

    • The sum of the interior angles of a quadrilateral is always 360 degrees.
    • The diagonals of a quadrilateral intersect each other, and the sum of the lengths of the diagonals is greater than the sum of the lengths of any two opposite sides.

    Theorems and Formulae

    • The midpoint theorem states that the line segment joining the midpoints of two sides of a quadrilateral is parallel to the third side and half its length.
    • The area of a quadrilateral can be calculated using the formula: Area = (b × h) / 2, where b is the base and h is the height.
