How to draw golden section segments using geometric sketchpad

The golden section is of great significance in geometry. This tutorial will explain in detail how to use the geometric sketchpad software to draw the golden section. The golden ratio is a special ratio that is considered visually beautiful and is widely used in fields such as art, design, and architecture. Mastering the method of drawing the golden section helps us understand the charm of this ratio more deeply and apply it to our own works.

1. Open the geometric sketchpad and click [Customize Tools] - [Proportion] - [Golden Section] on the sidebar.

2. Click the mouse in a blank position of the canvas to determine one endpoint of the line segment, and then move the mouse to a suitable position and click to determine the other endpoint position, as shown in the figure.
