Difference between Ptolemy's inequality and Quadrilateral
Ptolemy's inequality vs. Quadrilateral
In Euclidean geometry, Ptolemy's inequality relates the six distances determined by four points in the plane or in a higher-dimensional space. In geometry a quadrilateral is a four-sided polygon, having four edges (sides) and four corners (vertices).
