Draw a line segment and divide it in the ratio 2:5. Verify by measurement.

1) Take a line segment OG and taking any arc length draw a curve intersecting OG at Q

2) From Q with same arc length draw a curve intersecting the previous curve at P. Join OP and extend it

3) Taking P as centre and OP as arc length draw another curve intersecting OP at R. Similarly do for S, T , U , V , X

4) Join X to G and now draw lines parallel to XG from V , U, T, S, R , P intersecting OG at F , E, D, C, B , A respectively.

Thus our line is divided into seven segments Now OB:BG = 2:5
