MIKAELA’S GEOMETRIC SOLID PRESENTATION

By: Mikaela Y. Schmidt

Definitions

Rec. is rectangular Tri is triangular Face is a flat surface on a polyhedron An edge is a line segment where 2

faces meet. Vertex is a point where 3 or more

edges meet in a solid figure.

The Cube

The cube has SIX faces which are a FLAT surfaces on a solid figure or a polyhedron

The Cube also has 12 edges which is a line segment where 2 faces meet.

And don’t forget the vertices! The cube has 8 of them!!! Vertices are also known as corners.

The Cone

The cone you may know as the ice cream cone!

The cone has 1 face at the bottom.

The cone also has 1 vertex.

A funny thing about the cone is that it has 0 edges!!!

You might see these outside with Honor Patrol!!!

This is an ice cream cone!!

The Sphere

It’s the round one that looks like a ball.

It has 0 vertex, 0 faces and 0 edges.

Here are a couple of examples

The Cylinder

If you have seen a soup can or a soda can then you have probably seen a cylinder.

The cylinder has 2 faces on the top and on the bottom.

There is 0 edges even though there is 2 faces the never meet to make an edge.

This is an example of a cylinder!!

This object was found in our own office!! Shapes are everywhere

The triangular pyramid

The tri. Pyramid has 4 faces!!

It also has 4 vertex!!!

The tri. Pyramid has 6 edges! These can sometimes be hard to find!

The Rectangular Pyramid

The rec. pyramid has 5 faces.

Like any other geometric solid it has vertex, it has 5 of them!

It has 8 edges.

This is a rec. pyramid.

The Triangular prism

The Triangular prism has 5 faces!!

It has 6 vertex and 7 edges!!

Like the tri. Pyramid it can be hard to find

The Rectangular Prism

The Rectangular Prism has 6 faces and 8 vertex.

It also has 12 edges!! This is an example of a rec. pyramid.

You may find one in your house!
