Exploring ellipse shapes
- Chris Woodward
This applet allows you to explore how the transverse diameter (sum of distances from point on ellipse to the foci) and the distance between the foci affect the shape of the ellipse (e.g., very elongated, close to a circle, etc.). You can drag any of the points A, B, C in order to change the shape of the ellipse. Use this to answer the questions under the applet.
