Square is one of the most basic shapes. A square is a quadrilateral with four equal sides & four equal angles.
Basic properties of a square are:
- Equality
- Bisection
- Perpendicularity
Equality:
- Opposite sides of a square are parallel and equal in length.
- All four angles of a square are equal. (Each is 360°/4 = 90°, so every angle of a square is a right angle.)
- The diagonals of a square are equal.
- All four sides of a square are equal.
Bisection:
- The diagonals of a square bisect each other.
- The diagonals of a square bisect its angles.
Perpendicularity:
- All the angles of the square are equal to 90°.
- Diagonals meet at 90°.
