What Are Solid Geometric Shapes or Bodies?

Share on FacebookTweet about this on TwitterShare on LinkedIn

Surely, you know about flat geometric figures so today we are going to talk about solid geometric figures which are also known as geometric shapes or bodies.

These figures have three dimensions – length, depth, and height. In other words, these figures have volume and we can say that they occupy a place in space.

Geometric Shapes

Principal types of solid geometric figures
Polyhedrons

The word polyhedron comes from the Greek word “poly” which means many and from “hedron” which means base or seat. We are talking about geometric shapes that have multiple faces and are flat. Among them we have:

  • Regular polyhedrons: they are known as platonic solids and are characterized as having faces that are all equal. There are five: tetrahedron, hexahedron (cube), octahedron, dodecahedron, and icosahedron.

Geometric Shapes

  • Prisms: are composed of two polygonal bases, which are the same size and shape, and their lateral faces are parallelograms.Geometric Shapes
  • Pyramids: are made up of a polygonal face, which is its base, and lateral faces in the shape of triangles.

Geometric Shapes

In real life, we can find so many objects in the shape of polyhedrons, like an ice cube, a pyramid, or a carton of milk.

Geometric Shapes

Characteristics of Polyhedrons:

  • Face: the faces of a polyhedron are the flat surfaces on the outside of the polyhedron.
  • Edge: the edges of polyhedrons are made up of the sides that form each face.
  • Vertices: the vertices of a polyhedron are the points where the edges meet. Three faces meet on one vertex.

Geometric Shapes

Round Bodies

There are some solid geometric figures totally made up of curved and flat surfaces. Among those, the most common round bodies we can find are:

  • Cone: a round body composed of a circular base and curved surface.

Geometric Shapes

  • Sphere: a completely curved geometric body made up of a curved surface.

Geometric Shapes

  • Cylinder: a geometric body made up of a curved surface and two flat, circular bases.

Geometric Shapes

We can find many round body shapes in real life objects, like a volcano (cone), a billiard ball (sphere), or a paint bucket (cylinder). Geometric Shapes
