If the geometry sketchpad you downloaded is relatively new, it is probably in the help. Open the Geometer's Sketchpad and click the help above to see if there is a "control tutorial". If there is, just look there. Very detailed, with pictures. If not, look at the following methods, which may be rough:

1. Click the Insert Geometry Sketchpad File command under the Insert menu of PowerPoint2003, select the gsp file, and click in the ppt editing area. You can adjust the size of the sketchpad presentation area by dragging the handle left and right;

2.( 1) Click View → Toolbar → Control Toolbox → Other Controls in PowerPoint2003;

(2) Click "Other Controls" to find the command "1x Geometric Sketchpad Control", click and draw the control in the ppt editing area, and drag the handle left and right to adjust the size of the Sketchpad demonstration area;

(3) Click the Properties button on the Control Toolbox, or right-click Properties in the control box to open the Properties dialog box. In the gsp file, click "..." to select the gsp artboard file.
