These links give basic and in-depth information about JavaSketchpad, including how to use and produce JavaSketches. You may choose how to make the most effective use of the animated illustration that JavaSketchpad provides.JavaSketchpad (JSP) is software that lets you interact with-or publish-sketches from The Geometer's Sketchpad on the Internet. In contrast to our example on the first page, the applet here is embedded in this page, rather than opened in a new page. This version of the Sketchpad file can be downloaded and run (if Sketchpad is on your computer) - here is the working applet saved from it: As you will see when you click the applet link, only the unbroken objects survive.Ī work-around could be to draw a line segment in the first quadrant and animate the angle using a point on the line segment to locate the terminal side. The problem is that the current version of JavaSketchpad does not support the arc construction, which means the point cannot be selected on the arc, and so the Animate Objects button is broken as well. The applet saved is not functional, but the HTML page displayed in Sketchpad looks like this: 'Some objects in this sketch are not supported by this version of JavaSketchpad, and will not appear in your applet. This works in Sketchpad, but you can not save it from Sketchpad as a working HTML file. This approach is illustrated in the following Sketchpad sketch - to download the gsp file, click on the sketch. In Sketchpad you might use a horizontal line segment as one side of the angle, the arc command to create an arc in the first quadrant, a point on the arc to determine the terminal side, and an animate button to allow the point to move on the arc.

Suppose you want to provide your students an animated illustration of an acute angle.
