All The distances From the lens can be taken from a distance of 2cm and all the distances should be equal like F1,2F1,F2 & 2F2 should be of equal measure.

sorry for the word smistake
you can draw lens by using protractor 2cm above the principle axis and 2cm below the principle axis.

No! When The object is at 2F1 the image should come at 2F2
