Learn About Ellipse Geometry

An ellipse is a shape like a flattened circle. An ellipse has some important dimensions: the major axis and the minor axis, which when halved give the semi-major axis and semi-minor axis. It also has an area, which is the amount of space contained by an ellipse.

About This Widget

This widget allows you to find the semi-major axis, semi-minor axis, major axis, minor axis and area of an ellipse. Draw an ellipse by:

Semi-Major Axis:


Semi-Minor Axis:
Major Axis:
= 2 × semi-major axis

Minor Axis:
= 2 × semi-minor axis
Area:
= π × semi-major axis × semi-minor axis
