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?

Visual Logic Puzzle

  • $\begingroup$ I'd pick the triangles because it's the most different. Other than that, there is little to no logic on this puzzle. $\endgroup$ – greenturtle3141 Dec 31 '17 at 0:07
  • $\begingroup$ Yeah, I picked the triangles 'cause I thought maybe the left angle vs. right angle meant light vs. dark (the circles are not filled in while the triangles are) then I imagined the three bars on the last image as stretching the shapes into triangles. So, for example the left facing 3 bar one should be followed by three white triangles. It seemed to fit by process of elimination, but I can't see any direct logic. $\endgroup$ – James Bender Dec 31 '17 at 0:25

    $\begingroup$ I'm not sure it is a sequence so much as a set. Three of the answers are mirror images of the given patterns, the triangles pattern is the only one that isn't. $\endgroup$ – Jaap Scherphuis Dec 31 '17 at 20:14
  • $\begingroup$ There is no repetition so I would select the triangles as well. $\endgroup$ – Moti Jan 1 '18 at 7:45


..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.

    $\begingroup$ I like the thought, Jaap Scherphuis thought similar in his comment on the question. When you account for the fact that all the other options are mirror images for one that's already in the set and the fact that only one choice can be made, it does seem to stand out that the triangles image is the only one that is not a mirror of one of the given images. $\endgroup$ – James Bender Jan 2 '18 at 21:28

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

and also

If you see third image by half closed eyes(not sure whats the correct word) we can clearly see solid triangle!

    $\begingroup$ The word you were looking for is "squinting". $\endgroup$ – Rick van Osta Jan 2 '18 at 8:23
