Area of a quadrilateral calculator


Online calculator which will help you to find the area of a quadrilateral, its area is half the product of the diagonals multiplied by the sine of the angle between them, where (d1) is the diagonal of the quadrilateral, (d2) is the diagonal of the quadrilateral (α) is the sine of the angle between the diagonals.
A quadrilateral is a geometric figure that consists of four points (vertices), three of which are collinear, and four segments (sides), consistently connecting these points, there are convex and not convex quadrilaterals.
