Eccentricity of an Ellipse by Panagiota

This example demonstrates the eccentricity of an ellipse, a key parameter that describes the shape of the ellipse. By adjusting the semi-major and semi-minor axes, the change in eccentricity can be observed. The example uses commands and objects such as ellipse, segment, point, and angle in GeoGebra for construction. Suitable for high school mathematics education and learning about ellipse properties.
