Operation steps for drawing a rectangular circumscribed circle using the geometric sketchpad

php Xiaobian Yuzai will share with you the steps for drawing a rectangular circumscribed circle on the geometric sketchpad. In geometry, a rectangular circumcircle refers to a circle that can just wrap around the four vertices of a rectangle. Through simple geometric operations, we can easily draw a rectangular circumscribed circle and realize more interesting geometric figures.

1. Draw a rectangle. Open the geometric sketchpad, select [Custom Tools] - [Quadrilateral] - [Rectangle] in the sidebar, click twice on the canvas with the mouse to determine the two adjacent vertices, and you can draw a rectangle.

2. Select [Point Tool], add points to all vertices, and select [Display] - [Point Type] - [Medium] command, the effect is as shown in the figure Show.

3. Make a rectangular circumscribed circle. Select the sidebar [Customize Tools] - [Circle Tool] - a circle passing through three points (solid line), use the mouse to select the three vertices of the rectangle in sequence, and the circumscribed circle will appear, as shown in the figure.

The above is the detailed content of Operation steps for drawing a rectangular circumscribed circle using the geometric sketchpad. For more information, please follow other related articles on the PHP Chinese website!
