# KidZone Math Worksheets 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 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 =           where a is the length of an edge

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