Answer:With O as centre and radius BH, mark draw an arc and let it intersect the positive x-axis at M. M represents √7 on the number line. Hence √7 is represented on the number line.
Now, again draw a perpendicular at point B of length BC= 1 unit and join the points O and C. Again by pythagoras theorem we get OC = root 3. Then by compus taking radius =OC, draw an arc so that it cuts the number line at D. Then the distance OD will be the square root of 3.

Answer:
Representation of √2 on the number line.
Step 1: Draw a line segment of 1cm anywhere on a number line.
Step 2: Mark the line segment A and B.
Step 3: Draw a line segment of 1cm perpendicular to AB, and mark the point C.
Step 4: Draw a line connecting A and C.
Step 5: AC is √(12 + 12) = √2.
