So I'm taking a summer class at a local community college. My teacher assigned a project to us:

Task 2:
Cut up an equilateral triangle so that you can rearrange the pieces into two equally sized equilateral triangles.
Task 3:
Cut up a square so that you can rearrange the pieces and make an equilateral triangle.
What did you notice as you tried to figure out the solutions? Are these three problems related in anyway?

So how should i go about doing this? Is it even possible?
I managed to do Task 1 thumbsup.gif

Cut the equilateral down the middle for task 2.

You could cut a square diagonally but you would end up with an isosceles, so I'd have to think more on that one, but I'll do that later too :)

OO, sorry about that. For task # 2 I forgot to mention that they have to be equilateral.

Task 2: Umm.. I found a link that's kind of interesting. I'm not sure if it'll help at all.

Task 3: Your solution's right here. Here's how to make a triangle into a square and vice versa.
