小学阶段的学习中,孩子们会接触到一些比较简单的几何图形以及它们对应的规律和计算。在低年级时这些题通常比较简单,甚至可以一眼看出答案,这是为了培养孩子对图形的辨识能力和空间想象力。

而到了高年级和中学,几何题的难度会加大,可能看半天都看不出思路。所以,从小掌握基础图形的规律是很重要的!

我们先来看看基本规则图形:

这些都是最基本的内容,在面对高年级的组合图形计算时,这些都是印在脑子里的解题工具,是必须掌握的。

那么,不规则图形的面积及周长怎样去计算呢?

其实不规则的图形也是由规则图形变换出来的,我们可以针对这些图形通过实施割补、剪拼等方法将它们转化为基本图形的和、差关系,问题就能解决了。
