QUADRILATERAL
A quadrilateral is a polygon with four sides
A quadrilateral is a polygon with four sides. It is a two-dimensional shape with four vertices (corners) and four angles. The sum of the interior angles of a quadrilateral is always 360 degrees.
There are several types of quadrilaterals, each with different properties:
1. Square: All four sides are of equal length, and all four angles are right angles (90 degrees).
2. Rectangle: Opposite sides are parallel and equal in length. All four angles are right angles.
3. Parallelogram: Opposite sides are parallel. Opposite angles are equal, but they do not have to be right angles.
4. Rhombus: All four sides are of equal length. Opposite angles are equal, but they do not have to be right angles.
5. Trapezoid: At least one pair of opposite sides is parallel. The other two sides are not parallel.
6. Kite: Two pairs of adjacent sides have equal length. The diagonals of a kite intersect at a right angle.
7. Isosceles Trapezoid: Exactly one pair of opposite sides is parallel, and the other two sides are equal in length.
8. Regular Polygon: A quadrilateral with all sides and angles equal in length.
These are just a few examples, and there are many other types of quadrilaterals. Quadrilaterals have various properties and formulas that can be used to calculate their area, perimeter, and other measurements.
