How to use Geometric Sketchpad to draw points on two line segments to make the ratios equal

How to draw points on two line segments in Geometry Sketchpad to make the ratio equal? PHP editor Xigua today provides a detailed explanation of how to draw points on two line segments on the geometric sketchpad to make the ratios equal. For first-time users, this may seem like a complicated task, but by following our detailed steps, you will Master this skill easily. Read on to learn how to do exactly this.

For example, if there are two line segments AB and CD, take points E and F respectively, so that the ratio of points E and F to line segments AB and CD is equal. The specific operation is as follows:
