Question

How to represent root values on number line

Answer 1

Answer:-

1. Draw a line segment AB such that it is 7.5 cm long.

2. Now extend the line to a point C so that B is a point on the line segment AC and BC = 1 cm.

3. Find the midpoint of AC and name it O. Now, with O as the centre and radius equal to OA, draw a semi circle with AC as the diameter.

4. At point B, make an angle of 90 degrees such that the line intersects the semi-circle just drawn at a point D. Join DC.

5. With BD as the radius and B as the centre, draw an arc to cut the extended line segment AC at E.  

BE is the required line that is under root 7.5 units long

hope it helps :)
