    Area of square: [(side)²]
    Perimeter of square: [4(side)]
    Diagonal of square: [(side) (sqrt(2))]

    Related Article: A square can also be defined as a rectangle with all sides equal, or a rhombus with all angles equal, or a parallelogram with equal diagonals that bisect each other.

    1. The diagonals of a square bisect each other and meet at 90 degrees
    2. The diagonals of a square bisect its angles.
    3. The diagonals of a square are perpendicular.
    4. Opposite sides of a square are both parallel and equal lengths.
    5. All four angles of a square are equal. (Each is 360°/4 = 90 degrees, so every angle of a square is a right angle.)
    6. The diagonals of a square are equal.

    Example
    Calculate the Area, Perimeter and Diagonal of a Square whose length is 10 cm.

    Solution:
    Apply Formula:
    Step1Area of square: [(side)²]
    Area of square = 102 = 100
    Step 2Perimeter of square: [4(side)]
    Perimeter of square=4*10 = 40
    Step 3Diagonal of square: [(side) (sqrt(2)) ]

    Diagonal of square=10 * sqrt(2) =10*1.41 = 14.1
