Given the diameter AB of a cirle which lies in a 1st projecting plane (vertical plane). Construct the diameter CD perpendicular to AB
(in the cicle), moreover construct the essential diameters (which are
pojected onto the axes of the image ellipses). Draw the tangent lines
at the endpoints of the diameters and draw the images of the
circle. A(25, 90, 215); B(80, 35, 250).
