WebThe degree of flatness of an ellipse is measured by a parameter called eccentricity. An ellipse with an eccentricity of 0 is just a circle. As the eccentricity increases toward 1, the ellipse gets flatter and flatter. A … WebConstructing an ellipse An ellipse can be defined as the locus of points such that the sum of the distances from two fixed points to a point on the ellipse is constant. These two fixed points are called the foci. Based on this definition one can construct an ellipse using a piece of string, something to hold the string in place with and a pencil.
