Quadrilateral
a polygon with four sides
A quadrilateral is a polygon that has four sides and four vertices (corners). The sum of the interior angles of a quadrilateral is always 360 degrees.
There are several types of quadrilaterals, including:
1. Rectangle – a quadrilateral with four right angles
2. Square – a rectangle with all sides equal in length
3. Parallelogram – a quadrilateral with opposite sides parallel
4. Rhombus – a parallelogram with all sides equal in length
5. Trapezoid – a quadrilateral with one pair of parallel sides, called bases
6. Kite – a quadrilateral with two pairs of adjacent, congruent sides
Quadrilaterals can also be classified as convex or concave. A convex quadrilateral has all its interior angles less than 180 degrees, while a concave quadrilateral has at least one interior angle greater than 180 degrees.
Quadrilaterals are used in many different areas, including geometry, architecture, engineering, and art. They are often studied as part of geometry and are used to solve problems related to angles, lengths, and areas.
