Wrapping an Equilateral Triangle (Posted on 2005-10-10) Difficulty: 3 of 5
You have an equilateral triangle you want to wrap with a square piece of paper. If the triangle has unit sides, what is the smallest square piece of paper that can be folded around the triangle such that both the front and back sides of the triangle are completely covered by the paper?

Nicely done, Michael :) Yours does seem the best solution. There seems no better way to postion the folds.

This is also the solution of the simultaneous set y=cos30-xtan30 and y=x-cos30 yielding 2cos30/1+tan30 which gives the same result Michael obtained.

Does anyone else find that interesting?
