  • Draw a number line, mark a point O, at 0.
  • Now take 1 unit(with any measurment), mark it as point A.
  • Draw a ray AB, such that AB=1 unit,perpendicular to line OA.
  • Join OB.
  • Now, take your compass,with centre O and radius OB; draw arc intersecting numberline at C.
  • Point C represents root 2 on number line

easy.

draw a numberline....

u may hav to take 5 cm =1 unit to represnt it bigger.

mark 0 as O.now from 1 cm on the numberline, draw a line of 1 cm [ like making a right angle].mark it as A.join OA.with OA as radius draw an arc to meet the numberline.mark this point as B.this is root 2.

got it..... thumb ups pls..........
