Upon completing your 3D NET tasks this morning, work with a partner to solve the quiz problems on the link below…

Prisms are one of the three categories of **Polyhedrons**. Prisms are 3D shapes with parallel and congruent* end faces, with the shape of the pair of congruent faces giving each prism its name.

**Congruent figures have exactly the same shape and size.*

This morning we explored the definition of a ‘Polyhedron’ on our iPads. We came up with the following statements,

- a solid shape with many faces
- ‘hedron’ is Greek for faces
- Each face of a Polyhedron is a polygon
- ‘poly’ is Greek for many
- A polygon has no curved surfaces. It is a closed shape
- Polygons can be regular and irregular
- Polyhedrons can be classed into three categories – pyramids, prisms and platonic solids
- 3D shapes have faces, edges and vertices.
**Faces:**A flat individual surface of a solid object.**Edges:**Line segment that joins two vertices/ where two surfaces meet.**Vertices:**Corners, connects the shape together. The point where two or more surfaces meet.
