I am just telling the steps of making root 2 on a number line. You just make it. Steps are :- 1) Make a line of 1 cm and name the line AB. 2) Make angle B = 90 degree. 3) Open the compass on the scale and measure 1 cm. Then, cut an arc from point B and name the point as C. 4) Join the line from point C to point A. 5) AC = Root 2 6) Extend the line. 7) Now measure the length of AC and put the compass on A and make a dotted line on the line AB. Now I will tell you how AC is root 2 we had calculated. By Pythagoras theorem (Hypotenuse) square = (Base) square + (Perpendicular) square ( AC) square =(AB) square + (BC) square ( AC) square = (1) square + (1) square ( AC) square =1 + 1 ( AC) square = 2 AC = Root 2 Thank you.
