- Ellipse[ <Focus>, <Focus>, <Semimajor Axis Length> ]
- Creates an ellipse with two focal points and semimajor axis length.
**Example:**`Ellipse[(0, 1), (1, 1), 1]`

yields*12x² + 16y² - 12x - 32y = -7*.

- Ellipse[ <Focus>, <Focus>, <Segment> ]
- Creates an ellipse with two focal points, where the length of the semimajor axis equals the length of the given segment.
**Example:**Let*s = Segment[(0,1), (2,1)]*.`Ellipse[(0, 1), (2, 1), s]`

yields*3x² + 4y² - 6x - 8y = 5*.

- Ellipse[ <Focus>, <Focus>, <Point> ]
- Creates an ellipse with two focal points passing through a given point.
**Example:**`Ellipse[(0, 1), (2, 1), (1,2)]`

yields*1x² + 2y² - 2x - 4y = -1*.
