Given are the steps to draw a perpendicular to a line from a point outside the line, when the point is near an end of the line.Arrange the steps. Let AB be the line and P be the point outside the linei.The line ED is perpendicular to ABii.Now take C as centre and CP as radius cut the previous arc at two points say D, E.iii.Join E and D.iv.Take A as center and radius AP draw an arc (semicircle), which cuts AB or extended AB at C.

Geometrical Construction topics include: Parallel & perpendicular lines construction, drawing regular polygons and tangents, ellipse construction, parabola and hyperbola construction, cycloidal curves and spiral construction. Geometric construction is the process of creating geometric objects using a compass and a straightedge. It is a part of pure geometry, which does not use numbers, formulae, or a coordinate system.  Geometric construction involves drawing lines, line segments, shapes, circles, and other figures accurately using a ruler, a compass, or a protractor.  Related...
