Explanation:

Start with a square. This has all angles equal to $pi/2$ and all sides equal (let's say with length $l$ ). If you the square in half along one of the diagonals you will get two rectangle triangles with the catets equal to $l$ and both acute angles equal to $pi/4$ . The $tan(pi/4)$ will be the opposite catet divided by the adjacent catet which is:

$l/l=1$
