This is a tricky logic puzzle you can actually solve with materials you have lying around your house. You'll probably have more luck with this puzzle by using real matches than if you were to simply draw out some different combinations. Here's the match triangles logic puzzle: Make four triangles of equal size and shape using exactly six matches (which are also of equal length). How do you do it? Hint: You do not need to break, bend, or alter the matches in any way.
