Geometric sketchpad is a general teaching environment for mathematics and physics, which provides rich and convenient creative functions, so that users can write their own teaching courseware at will. Create a mathematics laboratory for users and provide an ideal environment for doing mathematics. Using this software, we can draw solid geometric figures well, and also dynamically demonstrate the unfolding process of geometric figures, which is very suitable for learning solid geometry in high school geometry. If you find it difficult to draw three-dimensional graphics and do animation, you can go to the only geometric sketchpad, check the learning tutorial in Chinese official website, and download a large number of courseware templates.
