A quadrilateral is basically a polygon with 4 four sides implying, 4 edges, 4 corners or vertices.
For any quadrilateral, it must satisfy the property;
For a quadrilateral ABCD, ∠A + ∠B + ∠C + ∠D = 360 °
Wherein  A, B, C & D are the interior angles of the Quadrilateral.
If a quadrilateral is not self-intersecting it is termed as a simple quadrilateral. Whereas, a complex quadrilateral is one in which we have a quadrilateral.
Based on their interior angles and position of diagonals, quadrilaterals are classified into convex and concave quadrilaterals.
