Represent √3 and √7 on number line​

Answer 1

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 2

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.
