To find the positive square root of a positive real number, we follow the following steps.
- Obtain the positive real number x (say).
- Draw a line and mark a point A on it.
- Mark a point B on the line such that AB = x units.
- From point B mark a distance of 1 unit and mark this new point as P.
- Find the mid-point of AP and mark the point as O.
- Draw a circle with centre O and radius OP.
- Draw a line perpendicular to AP passing through B and intersecting the semicircle at D. Length BD is equal to √x
