Point of intersection. Slope of the line Perpendicular distance. To calculate its features, the simplest way is to calculate the features of the two triangles which make up the crossed quadrilateral. CALCULATORS. Statistics calculators.

The calculation is done as follows: find the sum of the squares of the two adjacent sides of the angle, which is then subtracted from the square of the opposite diagonal. Midpoint.

What a cinch!
It uses the same method as in Area of a polygon but does the arithmetic for you. This article lists several calculators for area of a quadrilateral, There are several ways to calculate area of a quadrilateral. In this case it will be non-trigonometric Bretschneider's formula, Area of a quadrilateral given four sides and the fact that it is cyclic quadrilateral. Area of a quadrilateral given four sides and the fact that it is cyclic quadrilateral. Through this formula, it's possible to find out the area of any quadrilateral, no matter if it's a parallelogram, rhombus, trapezoid – in short, every 4-sided surface expect a crossed quadrilateral.
