Describe the features of three-dimensional objects (ACMMG043)

LO: To describe the features of 3-D shapes.

Know:

  • the basic features of 3-D shapes. (faces, edges and vertices)

  • the name and features of 2-D shapes.

Understand:

  • that 3-D shapes have unique properties which help to identify them.

Do:

  • I can describe the features of 3-D objects.

Different Types of 3-D Shapes

3-D shapes have 3 dimensions.

They usually have a length, width and depth.

Here are some common 3-D shapes that you should know.

Describing 3-D Shapes

One way to describe 3-D shapes is by determining their properties.

A face is the flat surface of the 3-D shape.

An edge is where 2 faces meet.

A vertex (vertice) is the corner of the 3-D shape.
