How to add a background picture to the geometric sketchpad?

There are two main ways to add background pictures to the geometric sketchpad. This is just a general introduction. For a more detailed tutorial, please visit/changjianwenti/Beijing-tupian.html.

Method one cancels the selected attribute of the picture.

Step 1: Open the Geometer's Sketchpad, select the picture to be used as the background, drag it to the editing area of the Geometer's Sketchpad, and resize the picture to the software window.

Step 2: Select a picture, right-click and select the "Properties" option. In the pop-up properties dialog box, there is an option of "You can choose". Remove the previous check and click "OK".

Method 2: Insert the background picture at a fixed point.

Step 1: Make an immovable point. Open the geometric sketchpad software, select the point tool to draw a point in the middle of the blank area of the sketchpad, use the selection tool to select this point, and right-click the mouse to select properties. In the pop-up properties dialog box, there is an option of "You can choose". Remove the previous check and click OK.

The second step is to copy the picture to the main point. Copy the picture to be used as the background to the geometric sketchpad, select the points and pictures, hold down the Shift key, and execute the command of "Edit"-"Merge Pictures to Points". At this point, the picture will be centered on the point and evenly distributed around the point.
