Hint 3 of 3
Find the key whose shapes are a square, then a triangle, then a circle in the same order.
Show solution
Approach: match the key's shapes to the keyhole, in order
- Read the keyhole from top to bottom: a square, then a triangle, then a round circle.
- The matching key must have those same three shapes in that same order: square, triangle, circle.
- Only key D has a square on top, a triangle in the middle and a circle at the bottom. The answer is D.
