Steps for constructing a line segment whose length is equal to the difference of the lengths of the two given line segments are:
(i) Now draw a line L.
(ii) Take two line segments AB and CD.
(iii) With P as a centre cut a length PZ equal to AB.
(iv) SZ is the required line Segment.
(v) Mark point P on the line L.
(vi) Now from P cut a length PS equal to CD.
ii, i, v, iii, vi, iv
Correct sequence is : ii, i, v, iii, vi, iv
(i) Take two line segments AB and CD.
(ii) Now draw a line L.
(iii) Mark point P on the line L.
(iv) With P as a centre cut a length PZ equal to AB.
(v) Now from P cut a length PS equal to CD.
(vi) SZ is the required line Segment.
