I don’t feel so bad. I’m still working on my algebra homework.

Glad this is solved.
Now for that single red sock that is missing from my laundry.

Pffft, I coulda told them that decades ago, but no one bothered to ask me! (I kid, I am terrible at maths)

A square has 4 corners. If you cut up an equilateral triangle trying to make a square you have to have at least four pieces.How else are you going to arrive at 4 corners?

Wow! Right on the nose!
To: Nateman
How else are you going to arrive at 4 corners? an equilateral triangle cut in to two pieces will produce 1 piece with 4 corners and 1 piece with 3 corners (one case - bisected - will produce to congruent triangles - each with 3 corners).
