Introduction: Triangle Illusion

How to draw the impossible triangle, by Penrose, the great illusionist that worked with Escher to make this.

Step 1: Step 1: the Triangle

First, start with a perfect triangle, like so.

Step 2: Step 2: the Extension

Extend the lines a little bit, like so. Sorry if its doesn't look the same.

Step 3: Step 3: Second Extension

Then add an Extension off the other extension, longer then the first line, like so.

Step 4: Step 4 : Extension 3

Extend off the extension you just did, this time the same length as the second extension. If you did not understand anything i just said, look down.

Step 5: Last Step

Now connect, like so.You're almost done!

Step 6: Step After Last Step

Shade ,like so. You are done! Please comment

    Ha, cool, now I can do this! Great job!

    This was not that hard to make once you followed the directing a couple of times. When you look at it the triangle looks really great

    this is soooo cool i have always wanted to dothis!!!

    awesome awesome 5 stars awesome awesome aswesome

    I'm actually a bit jealous that your method for drawing this may be simpler than mine! Good job!
    (Also - Do you mind checking out my 'ible on the Penrose triangle and giving your opinion on it?)

    I don't get it...how is it impossible?

    Could you carve this out of wood? I don't think so.

     Well, actually, you could. You ultimately FAIL!
