Abstract:
The paper deals with the problem of constructing a straight line perpendicular to a given line, and on constructing a line perpendicular to a given plane, as a rule, reduce to constructing the height of some triangle. In the general case this problem is a metric problem.
Keywords:ñonstruction of the perpendicular of the given line, height construction, length ratio, parallel projection, metric construction, diagonal section, remote drawing.
