Geometry Java Applet Gallery
Saltire's Geometry Gallery is a collection of Java applets showing interesting
geometry configurations. All applets are dynamic in that
user input can cause the configuration to change. In some cases,
points can be dragged. In other cases dimensions can be changed
via edit controls. Some of the applets feature animation.

| Applets in this gallery exhibit basic geometrical properties
of angles in parallel lines and circular configurations.
We also look at pythagorean triples and incircles. |
|
|
|
| Four triangle calculators are presented,
which allow for the triangle to be specified either by three
sides, two sides and the included angle, two sides and the non-included
angle or two angles and one side. In all cases the remaining
sides and angles are computed. |
|
|
|
| A number of advanced geometrical configurations are presented.
These cover theorems about common tangents to circles, Napoleon's
theorem on the incenters of equilateral triangles and a number
of textbook problems as well as an illustration of Casteljeau's
spline construction algorithm. |
|
|
|
| Four bar, six bar, and Peaucellier's straight line mechanism
are illustrated. |
|
|
|
| An atlas of algebraic formulas for geometry models, ranging from the radius
of the circumcircle to the length of the equilateral triangle in Napoleon's
Theorem |

All applets were created using Saltire's Geometry Applet
Generator.
We also have an overview of our web site
available.
