Hidden Shapes

▶  Watch: how to find a hidden shape5 min

The CLEAR method in five minutes — one real question, solved step by step.

What one looks like

One shape sits at the top. It is called the target. Underneath are five busy figures, and exactly one of them has the target hidden among its lines.

Have a look at the simple one beside this. The target has four straight parts; trace them round in order and every one of them lands on a line the figure already draws. That is the whole question — but notice how little it looks like the target once it is in there.

Four things are always true, and every one of them catches somebody out. The target is hidden at exactly the same size. Every part of it is drawn — nothing is faint, nothing is left out. It is never flipped, so a mirror image is never the answer. And whether it may be turned depends on one sentence above the picture, which is where the method starts.

👀 A simple one
Find the shape at the top hidden inside one of the figures below. It is the same size and the same way round. Every side of it is drawn as a line. Which figure hides it?

The method

Five beats: check the rule, look at the target, eliminate, align it, right? — and their first letters spell CLEAR.

  1. Step 1 of 5

    Check the rule

    Read the sentence above the picture before you look at anything. It says either the same way round — the shape sits at the angle shown — or it may be turned round, which allows any angle at all. Both say the same size, both say every part drawn, and neither ever allows a flip.
  2. Step 2 of 5

    Look at the target

    Count its parts and say them in order: "long flat top, down the right, a slope, a thin arm." Then pick the signature — the run of two or three parts you would never find by accident, like a cut corner with the short drop under it. Those stay joined to each other however far the shape is turned.
  3. Step 3 of 5

    Eliminate

    Hunt the signature, not the shape. Scan the five figures for that run of lines. Most figures do not have it, and most of the page dies here — before you have traced anything.
  4. Step 4 of 5

    Align it

    On what is left, put the signature down and walk the rest of the outline from it, part by part, in order, all the way back to the start. When a walk fails, name the part that was not there — that is the line to hunt in the next figure.
  5. Step 5 of 5

    Right?

    Two last checks, and they are the two the wrong answers are built from. Is every part there, including the short ones? And is it the same size — hold the target's longest part against the one you found.

The shape will not pop out at you. It looks like four or five lines with other lines crossing them, and expecting it to jump out is why children freeze here. Allow 25 to 30 seconds each; an easy one takes 12, so bank that time for the hard ones.

💡 Worked example
Find the shape at the top hidden inside one of the figures below. It is the same size, but it may be turned round (rotated). Every side of it is drawn as a line. Which figure hides it?
How to answer

Watch for these traps

Try these yourself

Now have a go yourself — tap the figure that hides the shape.

✏️ Question 1
Find the shape at the top hidden inside one of the figures below. It is the same size and the same way round. Every side of it is drawn as a line. Which figure hides it?
✏️ Question 2
Find the shape at the top hidden inside one of the figures below. It is the same size, but it may be turned round (rotated). Every side of it is drawn as a line. Which figure hides it?
✏️ Question 3
Find the shape at the top hidden inside one of the figures below. It is the same size and the same way round. Every part of it is drawn — the straight parts as lines and the curved parts as curves. Which figure hides it?
