A method of cutting a pyramid in a geometric artboard

A lot of teachers in the use of geometric drawing board, found that the geometry of the artboard can not only draw some static diagram, but also according to the teaching needs to draw some dynamic diagram. For example, in the study of the pyramid, teachers can use geometric artboards to achieve the three-pyramid rotation and the side of the animation process, which makes the curriculum more interesting and easier for students to accept understanding. This geometry artboard Tutorial will introduce you to the method of cutting three-sided pyramid in the geometry of the artboard?

The following steps are described:

Step one draws a pyramid. On the method of drawing the pyramid in the geometry artboard there is no more introduction, you can refer to the tutorial: How to draw a pyramid with a geometric artboard.

To draw a three-pyramid example in a geometry artboard

Step two determine a polygon on a triangular pyramid. Click on the sidebar "point tool" and draw three points above the three edges of the pyramid, as shown in the vertex that determines a polygon.

Draw a sample of three points on the three edges of a triangular pyramid

Step three Select the sidebar "line ruler tool" to connect three line segments respectively. With the mouse selected three points, click the "construct"-"Triangle inside" command above the menu bar, as shown in.

Select the polygon inner sample under the construction menu

Step four after performing the above operation, you can see the three pyramid inside a polygon, as if it was cut,.

Example of a constructed triangular pyramid section

The above gives you a detailed explanation of the method of cutting triangular pyramid in the geometrical drawing board, when studying the related properties of triangular pyramid, it is often segmented, so as to facilitate further study. The segmentation process cannot be demonstrated on the blackboard, and the animation process of cutting the pyramid can be demonstrated dynamically with the geometry artboard.
