Today were going to discuss the properties of shapes. We will be looking at both 2D and 3D shapes when discussing their properties. There are different words that we use when talking about 2D and 3D shapes.
When looking at 2D shapes we use the following terms:
Lets have a look at a few 2D shapes and discuss the properties of these shapes.
A circle has 1 Side (it goes all the way around).
It has 0 Vertices (no sides meet).
It has an infinite amount of Lines Of Symmetry.
A Triangle has 3 Sides.
It has 3 Vertices.
It has 3 Lines Of Symmetry (see image below).
In your books, write down the properties of the following shapes.
3D shapes use the following terminology:
Let have a look at a 3D shape and discuss its properties.
The cube has 6 Faces.
The cube has 8 Vertices.
The cube has 12 edges
In your books tell me the properties of the following 3D shapes.
Now go onto Purple mash and complete the 2do that has been set.
