Add another one of the stacks that has the top brick turned. After adding 6 more stacks attach another stack with a turned piece. Finally, attach the rest of the stacks as normal. 

Step 6:

Bring the two ends together to form a triangle. It will be a tight fit but it will snap together with a little pressure. Now experiment with different color designs and sizes.

Wow, you have so many awesome Lego Instructables! Legos were my childhood :) This bendy Lego stuff is super cool!

I dont normally comment on lego stuff but this is pretty neat stuff. I used to have 90lbs of them before I sold them all.

Well thanks for thinking this was neat enough to comment on :) I'm jealous of your 90lbs stash (even if you sold it). I have over 27k pieces but that doesn't include any of the basic bricks. I don't know how much my collection weighs but I'm still fantasizing about a 90lb bin haha

I don't know if I have enough 1x2 bricks to even make one of these, haha. They are SO expensive.

They look like giant Trivial Pursuit wedges. I like 'em.

jbrecken said that too! I do have more dark pink 1x2s now but I still don't know if it's enough :(

this is great and it can also be done with duplo 2x2 blocks and 6 2x4 blocks. you have reignited my love of lego. thanks

I just had an idea, if you put 5 of these onto the flat sides of the lego pentagon you get a lego star!

post a picture if this works.

That means a lot coming from TheAwesomestDude :)

If you stuck six of your Lego triangles inside your Lego circle, you could make a giant Lego Trivial Pursuit gamepiece.

I LOVE IT!! If I can get my hands on enough of the dark pink 1x2s I will have to do that.

thats not not a triangle! it's sides can not be curved!, go geometry!

It's not a triangle in a Euclidean plane, but possibly in a parabolic plane.

Thanks for following on YouTube.

No problem, I like Legos, so it seemed logical. =)

You're right, it's "not not a triangle" :) I say 3 sides, 3 angles is a triangle in my book. Maybe a Reuleaux triangle such as in a Wankel engine (rotary engine) but a triangle nonetheless.
Stop hatin and enjoy the Lego shapes.

Nope. There are more to come though but you'll just have to wait and see what they are.
