Get ready to be a code breaker!
Each of the shapes below has a matching code. We need to crack the code and then apply it to an extra shape.
In this type of question, the first thing we need to look for is a letter that appears as a code more than once.
We can see the letter L three times.
What do the three shapes linked by the letter L have in common?
They are all shaded black, so the letter L must mean that a shape is shaded black.
So the letter M must mean that the shape is not shaded.
We must give the final shape the code letter M, as it is not shaded.
Let’s try another one:
Which code should the final shape have?
Let’s look for a letter that appears as a code more than once…That’s right, we can see the letter T twice.
What do the two shapes linked by the letter T have in common?
Both of these shapes have a perimeter of a dashed line, so the letter T must mean that a shape has a dashed line perimeter.
We can also see the letter P appear twice as a code.
Both of these shapes have a perimeter formed of a normal solid line, which must mean that the code P is used for shapes with solid line perimeters.
Our final shape needs to use the code P as it has a perimeter which uses a solid line.
It’s now your turn to crack some codes!
Good luck detective.
