I know that a² + b² = c² But I'm afraid you² + me² ≠ we² You took the us out of Pythagoras So I turned 90° twice and walked away I had to say Adieu to hypotenyou I've forgotten you We were one whole polygon We got chopped in two Goodbye to the function of u + i You were my cosine But love triangles never work There's one too many sides Love triangles never work I know that π's digits are never-ending But you and I hit our limit, let's stop pretending You never let us be equilateral I was always secant, so I walked away I had to say Adieu to hypotenyou I've forgotten you We were one whole polygon We got chopped in two Goodbye to the function of u + i You were my cosine But love triangles never work There's one too many sides Love triangles never work Someone always ends up hurt We'll never be like what we were Love triangles never work Someone always ends up hurt We'll never be like what we were Love triangles never work!
