Properties of Quadrilaterals
A quadrilateral is a polygon with four sides. Quadrilaterals can be classified into several types based on their properties. Here are the properties of some common quadrilaterals:
Square:
- All sides are equal in length.
- All angles are right angles (90 degrees).
- The diagonals are perpendicular and bisect each other.
Rectangle:
- All sides are equal in length.
- Opposite angles are equal.
- The diagonals are perpendicular and bisect each other.
Rhombus:
- All sides are equal in length.
- Opposite angles are equal.
- The diagonals are perpendicular.
Trapezoid:
- Two sides are parallel and the other two sides are not parallel.
- The angles between the parallel sides are equal.
Parallelogram:
- Both pairs of opposite sides are parallel and equal in length.
- The opposite angles are equal.
- The diagonals bisect each other.
Kite:
- Two pairs of adjacent sides are equal in length.
- The opposite angles are equal.
- The diagonals are perpendicular.
In summary, a quadrilateral is a polygon with four sides.
