There are four sizes of points to choose from, and any combination of four widths and four patterns can be used for paths, such as straight lines or trajectories. You can use the marking tool to create angle markers, mark equal angles or right angles, and measure angles through angle markers. You can use the marking tool to create marks to identify paths and mark equal line segments or parallel lines.

According to your own preferences, create a frame to display polygons, or hide the interior of polygons; You can set the transparency of pictures, interiors or tracks and their iterations.

The function display mode can be selected as y=, f(x)=, and so on. , and can be displayed by selecting >; Edit | Settings | TextSet the default display mode of the new function, or use the Equation pop-up menu of the calculator to select it.

In radians, the display angle can be expressed as π or decimal; Customize the transformation by any two points (one point is associated with the other). For example, this transformation can be applied to almost any other object.

Applying the Geometer's Sketchpad to the "Inquiry Learning" in the mathematics classroom will make students willing and really have the opportunity to explore independently, instead of being dragged by the teacher to get the result of the problem directly. With the help of geometry sketchpad, the beauty of mathematics is embodied and students' interest in learning mathematics is stimulated. In the past, in order to make students feel the beauty of mathematics, teachers spent a lot of energy and physical strength to collect information, draw pictures and even color on the blackboard endlessly.

Nowadays, by using the dynamic jigsaw puzzle of the geometric sketchpad, we can draw beautiful pythagorean trees, combinations of rotating and transforming squares and a series of figures that can reflect the beautiful side of mathematics.

Abstract mathematical concepts can be visualized with the help of geometric sketchpad. Concepts in mathematics are often abstract and difficult for students to understand, which is a difficult point in mathematics teaching. If we can apply the geometry sketchpad teaching, we can visualize some concepts, make the knowledge simple and clear, and make it easier for students to accept. For example, when learning the concept of "axis symmetry", using the geometric sketchpad to demonstrate can not only attract students' attention, but also master the learning knowledge.
