Definition of Ellipse
Loading the math board and drawing, please wait…
This example demonstrates the definition and geometric construction of an ellipse. Key math concepts include ellipse, linear functions, and geometric construction. Using GeoGebra commands such as Point, Ellipse, Rotate, Angle, Ray, Intersect, and Segment, the formation process of an ellipse is visually presented. Suitable for high school mathematics education to understand the basic properties and construction methods of ellipses.

AI Drawing Prompt Reference
Draw an ellipse to demonstrate its definition and geometric construction. Start by plotting a horizontal line and marking a point. Use this point as the center and two fixed points to draw the ellipse. Rotate one of the fixed points around the center by a certain angle, then draw the rotated point and a ray. Find the intersection of the ellipse with the ray, and connect the intersection point to the center and the two fixed points to form the geometric construction, clearly showing the formation process of the ellipse.
