Found this practice visual puzzle online. The top image is the sequence, and the bottom image (with 4 options) is the options for the final shape set in the sequence. The answer is the three black triangles. Can anyone explain the solution?
..it is asking the question: What image is missing? Since all of the other images are present (whether they're mirrored or not) the answer should be the triangles.
I am not sure if its correct but could be:
the second image is drawn top view of first like the top view of first rods is circle and top view of the third image can be triangle(if rod not perfectly straight or looking from an angle).
we can just consider the ends of rod; for first image its round and for third its triangle
If you see third image by half closed eyes(not sure whats the correct word) we can clearly see solid triangle!
