The side length of a square with an area of 2 is √ 2. If the area is 2, the length of the two intersecting lines in the middle of the square is 2, and half of the length of the intersecting lines is 1. So as shown in the figure, draw four isosceles right triangles with exactly the same waist length of 1 (area of 1 / 2) from O, and they will become two exactly the same waist length of √ 2 (area of 1

How to draw a line segment of irrational length in the Geometer's Sketchpad

You can use the consolidation theorem of right triangle to draw the rational number of two right angle sides, and the hypotenuse may be irrational. As long as the value you use is not exactly the square of the rational number, you can do it. For example, if the two right angle sides are 5cm, the hypotenuse is 5 * and 2
