Let BC be a given segment to be divided into N equal parts. Draw any line through B at a positive angle to BC. Measure on that line equal segments BB_{1}, B_{1}B_{2}, ..., B_{N-1}B_{N}. Join B_{N} to C and through the rest of points B draw the lines parallel to B_{N}C. They will cross BC in the points dividing BC into N equal parts.
