Plato compared the platonics basing on their shapesġ. These simple representations made an impact on the people, so the solids are named after him as Platonic solids. It was mentioned in the book Timaeus by Plato. He recognised the beauty and mathematical significance of the solids, he hypothesized all of them, associating each regular with the classic elements of the universe, they are fire, sky, water and earth. Plato (427- 347 BCE) who lived around the same time as Theaetetus, learnt about the solids. After a few years, Theaetetus (417-369 BCE) another Greek mathematician discovered the other two solids octahedron and icosahedron, and was the first to give the mathematical description of all the five solids. Later one of the followers of Pythogars, named Hippasus discovered the dodecahedron. There is a strong claim that Pythogars is the first person who knew about the cube and tetrahedron solids. Pythogars (560 – 480 BCE) was a Greek philosopher and mathematician who was born in the town of Somas. There are only five regular polyhedrons, and they are “Platonic solids” 5 Platonic Solidsīoth polygons and polyhedrons are together called “Polytopes.” There are two types of polyhedrons they are regular and irregular polygons.Ī regular polyhedron consists of regular polygons.Īn irregular polyhedron consists of polygons with different shapes. Poly means many and hedra means face of the solid.Ī polyhedron is a three dimensional solid formed by joining polygons together. When more than two lines meet at a vertex they will form a three dimensional convex shape, which is known as a “polyhedron”. In a polygon, two lines meet at a point with an angle and the point where they meet forms a vertex (or is called a vertex). In an irregular polygon, the sides and angles are not equal. In a regular polygon, all the sides and angles of the polygon are equal. Lets learn some fundamentals of geometry before we start to explore about the platonic solids.Ī flat or plane two dimensional closed shape that consists of only straight lines without any curves is called a “polygon.” There are two types of polygons, they are regular and irregular polygons. In this article, we’ll explore the following topics mentioned in the index and you are encouraged to download and use the pintables and DIY activities related to platonic solids. Platonic solids are one of the most beautiful and unique solids ever discovered, among other things.
