Hiiii.....
An ellipse is a curve in a plane surrounding two focal points such that the sum of the distances to the two focal points is constant for every point on the curve.
No. of Ways .....
1. AUXILIARY CIRCLES METHOD
This is basically like stretching a circle out until it takes the shape of an ellipse.
2. THE PIN AND STRING METHOD
This method of drawing an ellipse has been used for hundreds of years. You can try it by sticking two thumbtacks in a sheet of paper and hooking a piece of string around them. Keep the string stretched with the point of your pencil and move your pencil around to trace an ellipse.
3. THE TRAMMELMETHOD
This is also a very old method of constructing an ellipse, it was Archimedes who first used this method. You can try it by cutting out a strip of paper/cardboard and marking .
4. TO CONSTRUCT AN ELLIPSE IN A RECTANGLE
Divide the sections of the rectangle into a number of equal parts as shown.
Draw a line from the sub-sections on the sides of the rectangle to the top of the minor axis.
Project a line from the bottom of the minor axis to meet these lines and locate the points on the curve.
Axial symmetry can be used to locate the other half of the curve
5. AN ELLIPSE FROM A PLANE CUTTING A CONE
As can be seen from the drawing below, when a plane is inclined to the axis of a cone and cuts all the generators the section is an ellipse. To get the true shape of the curve you have to look in perpendicular to the cutting plane.

In mathematics, an ellipse is a curve in a plane surrounding two focal points such that the sum of the distances to the two focal points is constant for every point on the curve. As such, it is a generalization of a circle, which is a special type of an ellipse having both focal points at the same location

How do you draw an ellipse?
1. With the compasses' point on the center, set the compasses' width to half the width (major axis) of the desired ellipse. 2. Move the compasses' point to one end of the minor axis of the desired ellipse and draw two arcs across the major axis.
