Hint 2 of 2
The answer is the single shape that is missing from at least one of the pictures.
Show solution
Approach: check each shape against every picture
- Each picture is built from circles, squares and triangles in different mixes.
- Compare the four pictures: every one shows circles and triangles, but the green square is not in all of them.
- So the shape that cannot be seen in every picture is the square, choice D.
