From Rectangle to Square

cults3d

Why is a Square a Rectangle? Many people wonder why a square is considered a rectangle. The reason is simple: a square possesses all the characteristics of a rectangle. However, explaining this concept to children requires a more engaging approach. Here's a design inspired by educators that can help make this idea clear: Imagine starting with a basic rectangle and repeatedly dividing it into smaller rectangles, until you eventually reach a square. This process demonstrates how a square is essentially a type of rectangle, albeit one with specific dimensions. Therefore, a square can be seen as the final stop in an infinite sequence of rectangles. Two versions of this design are provided: Version A features an inner square measuring 50mm by 50mm and can be easily disassembled; Version B has a built-in groove that requires some force to separate but still allows for reassembly. By playing with these shapes, you can gain a deeper understanding of mathematical concepts and have fun while doing so!
