Steps are given to draw an ellipse by trammel method. Arrange the steps. i. Place the trammel so that R is on the minor axis CD and Q on the major axis AB. Then P will be on the ellipse. ii. Draw two axes AB and CD intersecting each other at O. iii. By moving the trammel to new positions, always keeping R on CD and Q on AB, obtain other points and join those to get an ellipse. iv. Along the edge of a strip of paper which may be used as a trammel, mark PQ equal to half the minor axis and PR equal to half of major axis.

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.
If information about the major and minor axes of ellipse is given then by how many methods can we draw the ellipse?
