Shape A changes into shape B by one transformation — growing, shrinking, changing colour, gaining or losing a side, rotating, or switching between filled and hollow. Shape C needs the same transformation applied.
Rules
Work out exactly what single transformation turns shape A into shape B.
Click the option that shows shape C changed by that same transformation.
You’ll see immediately whether you were right, plus a plain-English explanation of the transformation.

Tips
Name the transformation in one word first (bigger? a different colour? one more side?) before you look at the answer options.
