Geometric artboards demonstrate the techniques of square piecing

As a professional drawing tool, the geometry artboard can be used not only to draw geometry, but also to assemble and compose new graphics by its animation function. For example, can you put two small squares together into a large square? In fact, as long as meet certain conditions, such a patchwork is also possible. Let's learn how to make a piece of a square in a geometric artboard.

Thinking Analysis: Will two the same small square, according to the diagonal split four small triangles, the four small triangles four right-angled vertices coincident, right-angled edge 22 coincident, you can form a new square.

A sketch of a dynamic demonstration square made by a geometry artboard:

Geometry Artboard Courseware Template--dynamic demonstration of the patchwork process of a square with an area of 2

In this courseware, click the "splicing" Operation button, you can dynamically demonstrate the small square along the diagonal cut, divided into 2 right triangle, and then right triangle will automatically move to the right, and then move the remaining three right triangle to the right, so that 4 straight-angled vertices coincident, 22 coincident edges, This makes it possible to spell a square with an area of 2, at the far right. If you want to go back to the initial state, click the "Restore" action button.

By clicking on the "Download template" button below, you can download the courseware to dynamically demonstrate the patchwork of squares and show students how to cobble together a square of 2 squares with 2 square 1 squares to deepen the understanding of the students. In fact, you can not only use the geometric artboard to make two small squares into a large square animation, you can also make semi-circular pieces of animation, the specific courseware can be consulted: the use of geometric artboard to make semi-circular patchwork animation.
