• Put the statements in an order to divide the line AB into 10 parts using the principle of diagonal scales. i. Number the division-points as 1, 2, 3, up to 9 starting from C and later join AC. ii. Divide the line BC into 10 equal parts. iii. Draw a perpendicular line BC TO the line AB. iv. Hence 9’9 is 0.9AB and similarly, other 2’2 is 0.2AB. v. Number the cutting points on AC as 1’, 2’, 3’ and so on up to 9’. vi. Draw lines parallel to AB through the division-points.

  ক

  L.C = 1V.S.D – 1M.S.D

  n*M.S.D = (n-1)*V.S.D

  গ

  n*M.S.D = (n-2)*V.S.D

  ঘ

  n*V.S.D = (n+1)*M.S.D
