Procedure:

  1. Draw a line segment OP1 of unit length (Let OP1 = 2cm).
  2. At P1 construct an angle of 90 degrees. Let the new ray be P1X, such that angle OP1X = 90 degrees.
  3. Cut off P1P2 = 2cm on P1X.
  4. Join OP2.
  5. Find OP2 using Pythagoras theorem. OP2 = Sqrt (2)
  6. At P2 construct an angle of 90 degrees. Let the new ray be P2Y, such that angle OP2Y= 90 degrees.
  7. Cut off P2P3 = 2cm on P2Y.
  8. Join OP3.
  9. Find OP3 using Pythagoras theorem. OP3 = Sqrt(3).

as u must have seen in video 1 of lesson 7 chapter 1 to construct root 2 and root 3 on the same graph that type of method of constructing irritional no is called squar root spiral
