Steps are given to draw an ellipse by loop of the thread method. Arrange the steps.i.Check whether the length of the thread is enough to touch the end of minor axis.ii.Draw two axes AB and CD intersecting at O. Locate the foci F1 and F2.iii.Move the pencil around the foci, maintaining an even tension in the thread throughout and obtain the ellipse.iv.Insert a pin at each focus-point and tie a piece of thread in the form of a loop around the pins.

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...
