How can we describe these
shapes?
![Page 15: 3D Shapes · 2020-05-07 · All 3D shapes have vertices/corners apart from a sphere. We can also say what shape the face is. The face is the shape of a square. Using these words,](https://reader033.fdocuments.us/reader033/viewer/2022042315/5f039aa17e708231d409df16/html5/thumbnails/15.jpg)
We can use words like…
Faces
Edges
Corners/Vertices

EDGES
All 3D shapes have edges apart from a
sphere.

CORNERS OR VERTICES
All 3D shapes have vertices/corners
apart from a sphere.
![Page 19: 3D Shapes · 2020-05-07 · All 3D shapes have vertices/corners apart from a sphere. We can also say what shape the face is. The face is the shape of a square. Using these words,](https://reader033.fdocuments.us/reader033/viewer/2022042315/5f039aa17e708231d409df16/html5/thumbnails/19.jpg)
We can also say what shape the
face is.
The face is the
shape of a
square.
![Page 20: 3D Shapes · 2020-05-07 · All 3D shapes have vertices/corners apart from a sphere. We can also say what shape the face is. The face is the shape of a square. Using these words,](https://reader033.fdocuments.us/reader033/viewer/2022042315/5f039aa17e708231d409df16/html5/thumbnails/20.jpg)
Using these words, how could we
describe a cube?
It has…
•6 faces that are
square shaped
•12 edges
•8 vertices

Can you go back through the shapes and
describe their properties?
How many corners/vertices do they have?
How many faces?
How many edges?
