Steps for constructing a line segment whose length is equal to the sum of the lengths of the two given line segments are:
(i) Draw two line segments AB and CD using a ruler.
(ii) Now take a line L.
(iii) PM is the required Line segment.
(iv) Using the compass a cut a line PQ equal to AB on line L.
(v) Now from Q cut a length QM equal to CD.
i, ii, iv, v, iii
Correct sequence is: i, ii, iv, v, iii
Draw two line segments AB and CD using a ruler.
Now take a line L.
Using the compass a cut a line PQ equal to AB on line L.
Now from Q cut a length QM equal to CD.
PM is the required Line segment.
