N7. Locate V10 on number line.

1.	N7. Locate V10 on number line.
Answer» We can do it by using PythagorasTheorem. We can write√10 =√(9 + 1) => √10 =√(3^2+ 1) Construction 1. Take a line segment AO = 3 unit on thex-axis. (consider 1 unit = 2cm) 2. Draw a perpendicular on O and draw a line OC = 1 unit 3. Now join AC with √10. 4. Take A ascenter and AC as radius, draw an arc which cuts the x-axis at point E. 5. The line segment AC represents √10 units.

Answer»

We can do it by using PythagorasTheorem.

We can write√10 =√(9 + 1)

=> √10 =√(3^2+ 1)

Construction

1. Take a line segment AO = 3 unit on thex-axis. (consider 1 unit = 2cm)

2. Draw a perpendicular on O and draw a line OC = 1 unit

3. Now join AC with √10.

4. Take A ascenter and AC as radius, draw an arc which cuts the x-axis at point E.

5. The line segment AC represents √10 units.
