Geometry Tools


Web Link: Geometry - GeoGebra

Flexibility: This app has the following functionality:

  • Creating shapes and regular polygons.

  • Creating points, lines, line segments parallel lines, perpendicular lines, bisectors, and other constructions.

  • Includes transformations for translation, reflect around the point, reflect about a line, and others.

  • Can add images and notes to the canvas

  • GeoGebra has been designed to create widgets, so line movement, growth, and expressions can be scripted.

  • Both their graphing calculator and geometry calculator can be used at the same time.

  • Can save the canvas to share with other students, teachers, or create a widget out of.

  • Can search for teacher resources here.

User Interfaces: Mouse and touchpad friendly. Somewhat touch-friendly, but recommended that a student downloads the app for the device they are one.

Browsers: Works with all major browsers.

Web Link: Desmos | Geometry

Flexibility: Desmos has the following functionality:

  • Creating shapes and regular polygons.

Web Link: Sketchometry

Flexibility: This geometry canvas sits on a grid and has the following functionality:

  • The points, lines, circles, and polygons are designed to be created by drawing on the screen.

  • Can insert expressions into the canvas.

  • Can add sliders to change expressions on the grid.

  • Performs several angle functions

  • Performs measurements on angles, lines, and polygons.

  • Might take a little bit of effort to get working properly.

User Interfaces: Mouse and touchpad friendly. Touch-friendly. It is actually designed to be used with touch.

Browsers: Works with all major browsers.

Web Link: Robocompass | A Robotic Geometry Box on 3D

Flexibility: This website shows how to make geometric constructions step by step. There are already over 20 examples of geometric constructions. After it is told what to do, it shows how each step would be done with a standard geometry set.

User Interfaces: Mouse and touchpad friendly. Touch-friendly, but small touchpoints.

Browsers: Works with all major browsers.

Web Link: Applet Gallery : Saltire Software

Flexibility: This website contains a number of geometry applets that show concepts in geometry.
