Show how `sqrt(5)` can be represented on the number line.

Explanation

wecan rewrite as `sqrt5 = sqrt((2)^2 + (1)^2)`

`sqrt5 ` is the hypotenuse

draw a perpendicular at 2 of unit 1 with hypotenuse `sqrt5` and draw a circle with that radius

the point touching the x point is the point where`sqrt5` lies on the number line.
