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.
