在小学阶段,同学们已经学过了一些图形与几何的知识,只不过大家学的知识是零散的、不系统的,那么在中学阶段,同学们将会比较系统地学习图形与几何的知识,探索图形的性质及其相互关系,加强对图形与几何的认识,发展空间观念,并借助图形的性质来解决一些实际问题,同时还要掌握基 In the elementary school stage, the students have already learned some knowledge about the figures and geometry. However, the knowledge we learn is fragmented and unsystematic. In the middle school stage, students will learn more about the knowledge of geometry and graphics. Explore the nature of the graphics and their relationships, strengthen the understanding of graphics and geometry, the development of space concepts, and with the nature of graphics to solve some practical problems, but also master
