I love brain teasers like this 
. It's amazing how simple problems can have multiple solutions and the smallest one can be really interesting. I mean, 50 being equal to both 1^2 + 7^2 and 5^2 + 5^2 is a nice touch 
. Not having all the answers right away makes it more fun too 
. And who knows, maybe solving these puzzles will even make my day a bit brighter

The math behind 'em is actually pretty cool too - all that symmetry and patterns... it's like uncovering hidden codes! 
I'm already thinking about the square pair problem, wondering if 50 really is the smallest solution. And that triangle test with just two possible strip lengths has got me intrigued... what kind of math does that involve?
