Quadrilateral's length of the diagonals
Description
A quadrilateral is a polygon with four sides (or edges) and four vertices or corners. The interior angles of a simple (and planar) quadrilateral add up to 360 degrees of arc.
The two diagonals of a convex quadrilateral are the line segments that connect opposite vertices.
The length of the diagonals in a convex quadrilateral can be calculated using the law of cosines.
