A four-sided planar shape (any one) made up of line segments is called a quadrilateral. Any quadrilateral will have the sum of its interior angles equal to 360 degrees. This shape maybe a trapezium, but not necessarily. A trapezium is a quadrilateral with no parallel sides, but it is possible to construct one with a couple of sides that are of equal length.
