Steps are given to draw normal and tangent to an archemedian curve. Arrange the steps, if O is the center of curve and N is point on it. i. Through N, draw a line ST perpendicular to NM. ST is the tangent to the spiral. ii. Draw a line OM equal in length to the constant of the curve and perpendicular to NO. iii. Draw the line NM which is normal to the spiral. iv. Draw a line passing through the N and O which is radius vector.

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...
