    • im cool like that

      they are the same length. it is the arrows at the end that make the bottom one look longer :D

  • Farted

    I have seen this illusion alot! They are both the same size!

  • sancho

    que putadas son esas they are the same


    Yeh this illusion is all about depth perception, the reason why one line looks shorter than the other is because our brains compare them to real life images (e.g. the corners of a room)

    Actually, they’re supposed to be further apart for the illusion to work!

    For pretty much any illusion that asks, “which is larger?” the answer is, “they’re the same size.” This is a pretty popular one and I’ve seen it a lot.

    you guys are all wrong. the top one is longer because, as the arrow indicates, it goes on forever

  • Anonymous

    Well, TECHNICALLY, if you think about geomety and lines and line segments, the first one would be longer since it would go on forever. BUT, if you look close, they are actually the same size.

  • nope the top one is longer because the arrows indicate the top line is endless and the bottom stay yhe same

  • luca

    the upper one is longer

  • its the same!!!
