Styles that would not have 4 sides or four angles or have curved sides or are open shapes are non-examples of quadrilaterals.
In almost any convex quadrilateral ABCD, the sum from the squares of your 4 sides is equal to your sum on the squares of the two diagonals moreover four times the sq. of the line section connecting the midpoints from the diagonals. Consequently
It's really a sort of quadrilateral with at least one among its inside angles measuring better than a hundred and eighty°. A concave quadrilateral has among its diagonals exterior the closed figure.
