Tangram is a fun jigsaw puzzle game, deepen children's understanding of graphics, especially graphics combinations! I think it can exercise children's spatial thinking and creativity! These are often subtle influences! The translation, rotation and other problem-solving methods commonly used in senior geometry problems are also a good basic understanding. As for the results? I don't think we should take it too seriously. I am Teacher Wang, and I focus on elementary school math! Today, I will introduce the basic knowledge of Tangram and the corresponding expanded question types.
Tangram
As the name implies, a jigsaw puzzle is seven graphic boards consisting of 5 triangles, 1 square, and 1 parallelogram, as shown in the figure below.
