Theoretically, countless figures can be drawn with three circles and three straight lines.

Extended data

Three circles and three straight lines are called geometric figures. Geometrical figures can help people describe the complex world effectively.

There are geometric figures everywhere in life, and everything we see is composed of basic geometric figures such as points, lines and surfaces. Geometry originated from western geodesy, which solves the relationship between points, lines and surfaces. The endless changes make the geometric pattern itself have endless charm.
