In this Shapes and Letters quiz, look out for different types of shading, such as bubbles or brick.
The figures in the boxes on the left hand side of the page have characteristics that have been given letters. A letter might refer to shape, outline, colour or shading or orientation. Some of the shapes have two letters, relating to two characteristics, and some have three letters, relating to three characteristics. Using this information you can find the code for the shape in the box on the right. There is a detailed explanation of how they work in the example question and answer.
