Given are the steps to draw a tangent to given arc even if center is unknown and the point P lies on it. Arrange the steps. Let AB be the arc.i.Draw EF, the bisector of the arc CD. It will pass through P.ii.RS is the required tangent.iii.With P as center and any radius draw arcs cutting arc AB at C and D.iv.Draw a perpendicular RS to EF through P.

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...
