# Square Root of any Real Number

### Notes:

Find Square Root of any Positive Real Number and Locate it on Number Line

Let say number is X

Mark the distance X units from a fixed point A on a given line to obtain a point B such
that AB = X units. From B, mark a distance of 1 unit and mark the
new point as C. Find the mid-point of AC and mark that point as O. Draw a semicircle
with centre O and radius OC. Draw a line perpendicular to AC passing through B and
intersecting the semicircle at D. Then, BD = X .
