Shapes with equal angles at teach of their corners, like squares or pentagons, are called regular shapes. But what do we call a shape with different angles, like a kite, a rhombus or a parallelogram? We call it an irregular shape. Irregular shapes have some odd names, like trapezium or even diamond!Cubes and pyramids are 3D shapes. Making three-dimensional shapes with card can be great fun and will give you an idea of how many faces a certain shape has.

Do you know the difference between a rhombus and a parallelogram? Test your knowledge of trapeziums, dodecahedrons and some other shapes in this quiz.
