Locating √5 on number line :
Here 5 = 2² + 1¹
..............[ See the attached image (I) √5 ]..........
So, draw a line a right angled OAB, in which OA = 2 units and angle OAB = 90°
By using Pythagoras theorem, we get
Taking OB = √5 as radius and point Pad centre, draw an arc which meets the number line point P on the positive side of it.
Hence, it is clear that point P represents √5 on the number line.
