Learn the power of Geometry Expressions by browsing through our many examples.
Altitude of a right triangle
A simple example to demonstrate Geometry Expression's constraint based approach to geometry and its symbolic output capability.
Geometry Expressions finds a surprisingly simple equation for distance from the midpoint of a trapezoid's side to its center.
Ellipse as a Locus
Here we demonstrate the usual string based construction of an ellipse foci (-a,0) (a,0).
Area of a Polygon
This example demonstrates how Geometry Expressions calculates area using either numbers or variables.
