Lab-08) Draw Ellipse -- ii. Parallelogram Method (On X and Y axis)

The parallelogram method of constructing ellipses inscribes the ellipse with in ellipses a parallelogram. You may use conjugate diameters or the major and minor axes to formulate the parallelogram so long as the sides of the parallelogram are parallel to the diameters or axes. To draw an ellipse by the parallelogram method, use this table; Steps: 1. Action Given the major and minor axes or the conjugate diameters AB and CD, draw a rectangle or parallelogram. Make sure all sides are parallel to their respective sides. 2. Divide the distance between AO and AJ into the same number of equal parts. 3. Starting at the ends of the minor axis CD, lightly draw straight lines through each point. The linesintersect forming the circumference of the ellipse. 4. Lightly sketch the outline of the ellipse. Darken the outline using French curves. Figure Illustrates the procedure for drawing an ellipse inscribed within aparallelogram
