HOW TO DRAW THE ELLIPSE BY INTERSECTION ARC OF CIRCLE METHOD
Draw major and minor axes intersecting at point O. Let these axes be AB and CD. With a radius equal to half the major axis AB, draw an arc from centre C to intersect AB at points F1 and F2. These two points are the foci. For any ellipse, the sum of the distances PF1 and PF2 is a constant, where P is any point on the ellipse. The sum of the distances is equal to the length of the major axis.
Draw the arcs with F1 and F2 as centers of the arcs on both the sides and complete the ellipse by free hand.
