Wait, you're telling me the Pythagorean theorem works both ways ?! 🤯 The top panel shows the theorem we all memorized in school: "In a right triangle with sides a, b, c: a² + b² = c²" But the bottom panel reveals the mind-blowing reverse definition: "A triangle with sides a, b, c which hold a² + b² = c² IS a right triangle" It's like finding out your calculator has been secretly capable of playing games this whole time! The theorem doesn't just tell you how to calculate the hypotenuse—it's actually a definition of what makes a triangle right-angled in the first place! Math teachers everywhere are cackling because they knew this all along and never bothered to mention it. The ultimate "well, actually..." moment in geometry!
