The missing square "tri"-angle

From a square be it geometry.
I see figure.
I can identify shapes.
I can exhibit my own self interest.
I am free to decide on what the mind registers.
My - own identity is.
That is?
That is!
A missing angle - unknown.
That not everything can be.
Can it not.
Exist not -
not exist.
The tall - tale of a fallacy.
The logically made up material.
Logic does.
