Answer» Answer: Make a line along the line ( on POINT M in such a way that point O joined with any point lie on OX,) that passes through point M and perpendicular to OM at M. From the point M, draw a line of 1 unit moving UPWARD, along the crease. Mark the point as N such that MN = 1 unit. Join ON, where ON = √3.
