Abstract:
We fold a triangle once along a straight line and study how small the area of the folded figure can be. It can always be as small as the fraction (2-sqrt{2}) of the area of the original triangle.This is best possible: For every positive number (varepsilon) there are triangles that cannot be folded better than (2-sqrt{2}-varepsilon).
