Shape A, B and C all have 4 sides and 4 corners, but can you see that Shape D has 5 sides and 5 corners. This is the odd one out. A shape with 5 sides and 5 corners is called a pentagon.

If you count the number of sides and corners on each shape you can work out the answer again. Shape A, B and C all have 4 sides and 4 corners, but can you see that Shape D has 5 sides and 5 corners.
