Orthodiagonal quadrilateral (altitudes of the four triangles)

Description

A quadrilateral is a polygon with four sides (or edges) and four vertices or corners. An orthodiagonal quadrilateral is a quadrilateral in which the diagonals cross at right angles. In other words, it is a four-sided figure in which the line segments between non-adjacent vertices are orthogonal to each other. For any orthodiagonal quadrilateral (ABCD), there is a relation between the altitudes of the four triangles formed by the diagonal intersection P and the vertices of the convex quadrilateral.
