Who knows what the professional geometry drawing software uses? For example, what software is used to make geometric figures in math textbooks and teaching AIDS?
In mathematics textbooks, the general drawing is completed with the help of geometry drawing board. This software contains many basic tools, which can easily draw the required graphics. With the help of the geometric sketchpad, draw a good picture, and then copy it to documents such as Word for use. The specific method is as follows:

Step 1: Open the Word document, as shown below. The layout in the document needs to be re-edited. Geometry, in particular, is not satisfactory and needs to be redrawn.

Figure 1: Open Word document.

Step 2: Open the Geometric Sketchpad and draw the corresponding geometric figures without letter marks, as shown below. Then select all the pictures, copy them with the shortcut keys "Ctrl"+"C", and save the pictures in the clipboard. You can use custom tools to draw the diagram, and the tutorial of adding custom tools to the geometric sketchpad can refer to: How to add custom tools to the geometric sketchpad.

Step 3: Create a new Word document and canvas, click Insert-Shape in the menu bar above, and click New Drawing Canvas in the drop-down menu, as shown in the following figure.

Step 4: Click on the canvas, and then use the shortcut key "Ctrl”+“V" to paste the picture into the canvas.

The fifth step is to insert letters into the picture inside the canvas: click the blank outside the canvas, then "Insert"-"Text Box" and click "Draw Text Box". Set the text box to the style of "No Fill" and "No Border". So you can enter letters in the text box. After writing the letters, copy and paste them on the canvas, and then drag them to the corresponding position. Finally, as shown in the figure below.

Tip: Click on the blank area outside the canvas to see the effect. Be sure to see the effect at any time. If it does not meet the requirements, it can be corrected in time to avoid mistakes!

The above is the skill of inserting geometric figures into Word with the geometric sketchpad, which is mainly to draw the figures in the geometric sketchpad and then copy and paste them into the Word document. For more skills, please refer to the official website of Geometry Sketchpad.
