Still stuck? Show hint 2 →
Hint 2 of 3
A shape you can build must be made of just three straight lines.
Still stuck? Show hint 3 →
Hint 3 of 3
Count the straight lines in each picture and keep the one that needs exactly three.
Show solution
Approach: match the count of straight lines
- Each stick stays one full straight line, so the shape can only have three straight lines.
- The star in option E is just three straight sticks crossing over each other.
- Every other picture needs four or more sticks, or asks a stick to bend.
- So the kangaroo can make shape E.
