Square is one of the most basic shapes. One of the quadrilaterals is a square of four equal sides & four equal angles.
Basic properties of a square:
- Equality
- Bisection
- Perpendicularity
Equality:
- Opposite sides of the square are parallel and equal.
- All four angles are equal in measure. (Each angle is 360°/4 = 90°. So that each angle is a right angle).
- The diagonals are equal in length.
- All four sides are equal in length.
Bisection:
- Diagonals bisect one another.
- Diagonals bisect its interior angles.
Perpendicularity:
- All interior angles are equal to 90°.
- Diagonals meet at 90°.
