3D square based pyramid

This is my 3D dimensional shape I made during class time, in maths we have been studding geometry, 2D and 3D shapes. 

Three things I learnt about geometry and shapes today was :

• That the face's of the shape is the flat sides on the shape.
• The edges are the straight lines around the 3D shape.
• Lastly the Vertex are the corners, the lines that join together.
