What are Quadrilaterals?
A quadrilateral is a two-dimensional figure created by connecting four segments endpoint to endpoint with each segment intersecting exactly two others. It also has four sides and four angles. Sum of interior angle of any polygon is (n-2) 180^o. Here quadrilateral has four sides so interior angle is (4-2)180^o = 360^o.Exterior angle of any polygon is 360^o so the exterior angle of a quadrilateral is 360^o.
