a^2 + b^2 > me^2

One is less than a combination of two
From Kumon days I have known this to be true
But only in San Francisco did I learn
How little of his theorem I truly knew

A triangle is made of three sides, indeed
For one to feel complete, two more are in need
As my mind set ablaze, I realized with glee
That from the front and back, I could not be freed

As two and one connected to become three
His theorem finally made sense, as you see
The sum of two squares is greater than the third
By Pythagoras’ theorem, they both dominated me
