How to use mathematical symbols in geometric sketchpad
Step 1: Open the geometry sketchpad software. When you need to insert a mathematical symbol, select the "Text Tool" in the left toolbar, and double-click anywhere on the drawing board to pop up a text box. At this time, a text toolbar will pop up below the sketchpad, as shown in the figure below.
Step 2: Click the rightmost symbol panel button on the text toolbar that pops up below the Geometry Sketchpad to open the symbol toolbar (as shown in the figure below), which contains many mathematical symbol panels and can be used to edit mathematical formulas.
Step 3 If these mathematical symbols are not enough, you can click the inverted triangle button on the far right, and a symbol panel will pop up (as shown in the figure below), which also contains many mathematical symbols and can be used when necessary.
