In term logic (a branch of philosophical logic), the square of opposition is a diagram representing the relations between the four basic categorical propositions.The origin of the square can be traced back to Aristotle's tractate On Interpretation and its distinction between two oppositions: contradiction and contrariety.However, Aristotle did not draw any diagram. This was done several centuries later by Apuleius and Boethius. (Wikipedia).

Find Side of Square from Diagonal | Geometry
How do we find the side length of a square when given the diagonal? We'll solve this square geometry problem in today's lesson! We'll simply have to note that a square is equilateral - meaning its sides all have the same length, and that square's have 90 degree angles. Thus, we'll be able
