This example demonstrates how to construct an ellipse as a locus. Key mathematical concepts include the locus definition in coordinate geometry. Using GeoGebra commands such as Point, Circle, and Intersect, the formation of the ellipse is visually illustrated. Suitable for high school mathematics education to help students understand the geometric properties of ellipses.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Circle(A, r) → c
  3. Circle(B, 20 - r) → d
  4. Intersect(c, d, 1) → D
  5. Intersect(c, d, 2) → E

AI Drawing Prompt Reference

Draw an ellipse by first taking a point A on the x-axis and drawing a circle c centered at A, then drawing another circle d centered at A with radius 20-r. The intersection of these two circles gives two points, take one of them as point D and the other as a point on the ellipse.
The prompt above was compiled from the original drawing commands and is for reference only.
