"Love Triangles (Adieu To Hypoten-You)" lyrics

I know that a² + b² = c²
But I'm afraid you² + me² ≠ we²
You took the us out of Pythagoras [paɪˈθæɡ.əɹ.əs]
So I turned 90° and walked away
I had to say

Adieu to hypoten-you
I've forgotten you
We were one whole polygon
But 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 wooooooork

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 hypoten-you
I've forgotten you
We were one whole polygon
But 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 wooooooork

Someone always ends up hurt
We'll never be like what we were
Love triangles never wooooooork

Someone always ends up hurt
We'll never be like what we were
Love triangles never wooooooork
