1. Plane graphics: rectangle, square, parallelogram, triangle, trapezoid and circle.

2, three-dimensional graphics: cuboid, cube, cylinder, cone.

Geometric graphics, that is, all kinds of graphics abstracted from physical objects, can help people effectively describe the complex world. 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.

Extended data:

Plane geometry can be divided into the following categories:

(1) circle: including perfect circle, ellipse and multifocal circle-ellipse. ?

(2) Polygons: triangles, quadrangles, pentagons, etc.

(3) Bows: excellent bows, poor bows, parabolic bows, etc.

(4) Multi-arcs: crescent moon, pattern, Tai Chi, gourd, etc.
