How to make graphics panning and rotating with geometric artboards

In maths teaching, teachers are not able to move when they are drawing on the blackboard. This is often not conducive to teachers to clear their own curriculum. If the graph can be moved and rotated as the course progresses, it will not only make the course lively and interesting, but also help students understand the memory points of knowledge. With the popularization of multimedia, geometric artboard is a very good tool. Here is the geometry of the drawing board course to introduce how to use the geometric artboard to make the graphics translation and rotation?

First, the use of geometric artboard to make the translation of graphics

To open the geometry artboard, select the Polygon tool on the left-hand toolbar, and draw any ABC in the blank area of the artboard, as shown in.

Blank area of artboard draws any ABC

Step two Select "Point Tool" in the white space to draw two points D, E, select the two points, perform the "Transform"-"flag vector" command.

Select the point D, E to execute the flag vector command

Step three Select the ABC you want to pan, perform the "transform"--"Pan" command, and click the "Pan" button in the pop-up translation dialog to get the translated triangle, as shown in.

Second, the geometric drawing board to make the graphics rotation animation

Here is also the example of the above-described ABC, the method of 180 degree rotation.

Step one marks the center of rotation. Here's an example of setting point C as the center of rotation, selecting the Select Arrow Tool, selecting the point C and double-clicking it, setting it as the center of rotation, or selecting point C to perform the transform-Mark Center command.

Step two use the Move Selection tool to select ABC, perform the "transform"--"rotate" command, enter the rotation angle in the popup dialog 180 degrees, and then click "Rotate" to get the ABC rotated 180 degrees after the triangle a ' B ' C, as shown in.

Above to you how to use the geometry of the drawing board to make the translation and rotation, for beginners of the geometry of the version of the Board of Friends, this is a very good introductory tutorial, is to master the geometric drawing board animation Courseware Basic tutorial, I believe that you have learned this tutorial, the drafting technology will be a higher level! If you want to get a geometry artboard, you can focus on the geometry artboard download .
