Divides a given line segment internally in the ratio of 1:3
Construction :i )Draw a ray AX making an acute angle with AB.
ii) Mark 4 points at equal distance. on AX
Let the first point be M and fourth point be N
iii) Join NB.iv) Draw a line parallel to NB through M.v) It meets the line AB at P.vi) P is the required point which divides AB in the ratio1:3 internally.
ii )
