Proof of the Irrationality of the Square Root of 2
($\sqrt{2}\in \mathbb{R}$)

There are various reasonings for the proof of the irrationality of the square root of 2. This article explains exhaustively the indirect proof variant and shows one of the possible abbreviated forms in mathematical notation. Exercises with solutions consolidate the acquired knowledge.

The duplex file versions have a type area optimized for duplex printers (two-sided print), the width of the margins vary dependening on odd or even page numbers.
