1, 3D graphics:

Cubes, cuboids, circles and cylinders.

2, plane graphics:

Square, rectangle and triangle.

Extended data:

Knowledge points induction of graphic classification;

Firstly, the known graphics are classified according to different standards.

1, classified by plane graphics and three-dimensional graphics.

2, according to whether the plane figure is composed of line segments to classify.

3. According to the number of edges of the graph. Through self-help classification, we can re-recognize the graphics and understand their characteristics.

Second, understand the application of the stability of parallelogram and triangle in real life.

1, and the number of edges of a triangle includes:

Isosceles triangle, equilateral triangle, arbitrary triangle.

2, triangle according to the angle classification includes:

Acute triangle, right triangle, triangle, obtuse triangle.
