BUILDING A STRAIGHT LINE PERPENDICULAR TO A GIVEN LINE

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.
