Given are the steps to draw a perpendicular to a line from a point outside the line, when the point is near the centre of line.Arrange the steps. Let AB be the line and P be the point outside the linei.The line EP is perpendicular to ABii.From P take convenient radius and draw arcs which cut AB at two places, say C, D.iii.Join E and P.iv.Now from centers C, D draw arc with radius (more than half of CD), which cut each other at E.

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...
