Geometry Nets - Tetrahedron

A tetrahedron is a three dimensional shape with four triangular sides.  It is a type of pyramid.

In this case, I've created a regular tetrahedron -- it is made up of identical equilateral triangles.

Explore the tetrahedron by cutting out the geometry net, folding it and gluing the tabs.

 

Tetrahedron - Plain:  you can trace this onto decorative paper or decorate it as you see fit

Tetrahedron - cute faces:   (color)   or   (B&W)

Holiday Tetrahedrons:

Tetrahedron - Christmas:   (color)   or   (B&W)

Tetrahedron - Valentine's Day:   (color)   or   (B&W)



 

Tetrahedron characteristics:

  • a platonic solid (a three dimensional shape made up of identical two dimensional shapes with the same number meeting at every vertex)
     
  • 3 triangles meet at each vertex (or corner)
  • 4 Faces
  • 4 Vertices
  • 6 Edges

 

 

Tetrahedron formulas:  These are too complicated for most children.  The shape is interesting because it is a platonic solid (a three dimensional shape made up of identical two dimensional shapes with the same number meeting at every vertex)  I would skip the formulas for it but here they are in case you feel differently.

Surface Area of a regular Tetrahedron = surface area          where a is the length of an edge

 

Volume of a Tetrahedron = volume of a tetrahedron                               where a is the length of an edge
