| View Cart ⇗ | Info
An illustration showing how to construct an ellipse parallel to two parallel lines A and B. “Draw a semicircle on AB, draw ordinates in the circle at right angle to AB, the corresponding and equal ordinates for the ellipse to be drawn parallel to the lines, and thus the elliptic curve is obtained as shown by the figure.”
