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

3D Shape – Types and Properties

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.

## Explain the rhombic prism!

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.
