A quadrilateral is a closed figure with 4 corners or vertices and 2- dimensional. The word ‘quadrilateral’ literally means four sides. Quadrilaterals can generally be of regular shapes like squares, kites, trapezoids or irregular as the one shown below.
Here is a quadrilateral ABCD.
A quadrilateral has 4 vertices, 4 equal sides enclosing 4 angles of 90 degrees and the sum of its interior angles is 360 degrees. A quadrilateral having 4 equal sides and 4 angles as 90 degrees is a square and which has all 4 angles as 90 degrees is a rectangle. Parallelogram, trapezium rhombus, and kite are some other types of the quadrilateral.
Quadrilaterals can be further classified into:
- Concave quadrilaterals.
- Convex quadrilaterals.
- Intersecting quadrilaterals.
