Customized tools can be made according to personal preferences and needs, and tools of various shapes can be produced, which greatly improves production efficiency and creativity. In addition, you can use custom tools in the geometric sketchpad to create regular polygons, stars, sectors and other graphics to achieve more exquisite effects. In this article, we will introduce you to the production methods and usage techniques of custom tools in Geometric Sketchpad, hoping to help everyone better use Geometric Sketchpad to create excellent graphic works.

Step 1 Preparation

Open the menu drawing board, click [Data] - New Parameter in the menu bar, in the [New Parameter] dialog box that pops up, fill in the upper value in the dialog box ( Fill in as many polygons as possible) and click [OK]. A box appears in the upper left corner of the canvas with the number of sides written in it. This is our new parameter. In the upper left corner of the OK button, a box appears with the number of sides written in it (fill in as many sides as you want). Click [OK]. In the upper left corner of the canvas, a box will appear with the number of sides written in it. This is our new parameter.

Step 2: Control the center regular polygon

1. To draw a regular polygon by fixing the center of the regular polygon, first click [Auto] in the left sidebar. Define Tools], select [Regular Polygon] - Positive n deformation (inner n ≤ 42).

2. Click the newly created parameter with the mouse, and a point will appear. This point is the center of the regular polygon to be made. Then drag with the mouse to draw a regular polygon of a certain size.

Step 3: Control the vertices of a regular polygon

1. To draw a regular polygon by fixing the vertices of the regular polygon, first you have to click [ in the left sidebar Custom Tools], select [Regular Polygon] - Positive n deformation (outside ≤ 42).

2. Click the newly created parameter with the mouse, and a point will appear. This point is a vertex of the regular polygon to be made. You can draw a regular polygon of a certain size by dragging it with the mouse.
