1] √10 = √3²+1²

2]draw a number line OC such that OA=AB=OC=1 unit

3] draw a perpendicular line from C of 1 unit [as √10 = √3²+

**] and name the point as C**

__1²__4] join O and C it will form a triangle

by pythagoras theorem

OC = √10

now taking the radius of OC in compass draw an arc touching the number line .

and that point will be √10 .

Draw a 3unit line and a perpendicular line of 1unit and then hypotenuse isroot 10
