Polyhedrons: The Faces of Shapes
Hello friends, welcome to a new Happy Learning video, today we are going to learn about the … Polyhedrons.
The word polyhedron comes from Latin, POLI meaning many and Edro, faces, so its name tells us that the polyhedrons have many faces.
Polyhedrons are geometric bodies formed by several polygons. They have volume, that is they occupy space in the three dimensions: width, length, and height.
A very important thing that you also have to know about polyhedrons is that they are formed by three different elements: faces, vertices and edges
Observe this building and we will go discovering the three elements. As you can see, this building is a polyhedron formed by quadrilaterals, which are polygons with four sides.
Well, the faces are the polygons that make up the polyhedron, the edges are the sides of the faces and the vertices are the points where three or more faces meet
Now observe this pyramid of Egypt and we will discover its faces, vertices and edges. Easy eh?
Polyhedrons can be classified in many ways but there are two types that we have to know. They are THE PRISMS and THE PYRAMIDS.
The prisms have two polygonal bases and the number of sides of the base are called triangular prism if it has three sides, quadrangular prism if they have four sides, pentagonal if they have 5, hexagonal if they have six and so on to infinity and beyond.
The pyramids have a single base and a common vertex where the edges of the lateral faces meet, so it is clear that the lateral faces will always be triangular. Like the prisms, they are called by the number of sides their base has ; triangular, quadrangular, pentagonal pyramid, etc …
Polyhedrons have infinite shapes and sizes. If you look around us there are many polyhedrons. We are surrounded by them; don’t you think? …
