approximate ellipse from the following given information: we have a major axis A-O-
B and a minor axis of X-O-Y (view A).
To construct this ellipse, perform the
following steps:

ELLIPSE.
Step 1.
Draw an arc of radius O-A, using point O as a center, such that it
intersects point A and an extension of line Y-O-X (view B).
Step 2.
Draw a straight line between points X and B (view B).
Step 3.
