An Observation

If A+B+C=AxBxC,
Then it is a triangle.

If A^2+B^2=C^2
It is a right triangle.

We must understand this about equalities.
Thereby,
If doing a proof,
And one has a formula
A+B
One cannot intuit from this
A+B=0
If in a geometric relation.
For the system of equations
Will define the parameter
Of how the function will equate.
A+B will only equate
In relation to the other sides
Of the Geometric Figure.
