Problem solving Key Points
1 How many different shapes can be formed by Join each square
combining four squares of equal size at their one by one.
sides? Shapes that are the same after being
rotated or flipped are considered the same.
2 Draw the different shapes that can be formed by Increase the number
joining the vertices of four squares of equal size. of squares by 1.
Shapes that are the same after being rotated or
flipped are considered the same.
Example
(Correct way) (Wrong way)
