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 B twice. What do both of these shapes have in common?
They are both white faces with no shading, so the letter B must be used at the start of the code if the smiley face has no shading.
This means that a letter R at the start of the code must mean that the face is shaded.
What feature could the letter T refer to?
Both images with a T in their code have triangles on their heads. This must mean that the letter T is the code to show a triangular ‘hat’, whereas S must mean a square ‘hat’.
The final image is shaded so it will start with an R and it has a square ‘hat’ so it will end with an S.
So the correct answer is RS.
Let’s try another one:
Which code should be given to the final shape?
Let’s look for a letter that appears as a code more than once…That’s right, we can see the letter S twice.
What do both of the images linked by the letter S have in common?
They both have squares as the outside shape, so S must indicate that the outside shape is a square.
This means that M indicates a triangle as the outside shape and T indicates a circle.
So our final image must start with a T as the outside shape is a circle.
P appears as the second letter when the cross is not shaded and L appears when the cross is shaded.
Our final image needs to be given the code TP.
T for the outside circle and P for having an unshaded cross.
It’s now your turn to crack some codes!
Good luck detective.
