Getting Started

Videos illustrating many of the features of Geometry Expressions

Triangle

Altitude of a Right Triangle

A simple example to demonstrate Geometry Expression's constraint based approach to geometry and its symbolic output capability.

Trapezoid

Trapezoid

Geometry Expressions finds a surprisingly simple equation for distance from the midpoint of a trapezoid's side to its center.

Ellipse

Ellipse as a Locus

Here we demonstrate the usual string based construction of an ellipse foci (-a,0) (a,0).

Area

Area of a Polygon

This example demonstrates how Geometry Expressions calculates area using either numbers or variables.
