Area of a convex quadrilateral (in terms of sides and angle θ of the diagonals)


Quadrilateral is a polygon with four sides (or edges) and four vertices or corners. The area of a quadrilateral can be calculated by the sides and the intersection angle θ of the diagonals of the quadrilateral ( so long as this angle is not 90).
