A quadrilateral is a polygon with four sides
A quadrilateral is a polygon with four sides. It is a geometric shape that consists of four straight sides and four vertices (or corners). The sum of the interior angles of a quadrilateral is always equal to 360 degrees.
There are different types of quadrilaterals based on the properties of their sides and angles. Some common types of quadrilaterals include:
1. Square: A square is a special type of quadrilateral that has all sides of equal length and all angles of 90 degrees.
2. Rectangle: A rectangle is a quadrilateral with all angles of 90 degrees. Its opposite sides are equal in length.
3. Parallelogram: A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel. Its opposite sides are equal in length.
4. Rhombus: A rhombus is a quadrilateral with all sides of equal length. Its opposite angles are equal.
5. Trapezoid: A trapezoid is a quadrilateral with at least one pair of parallel sides. It does not have any equal angles or sides.
6. Kite: A kite is a quadrilateral in which two pairs of adjacent sides are of equal length. It does not have any parallel sides.
These are just a few examples, but there are other types of quadrilaterals as well. The properties of a quadrilateral can help identify its type and determine its characteristics and measurements.
