This example demonstrates the definition of an ellipse. Key mathematical concepts include the foci, major axis, and minor axis of an ellipse. Using GeoGebra commands such as Ellipse, Line, Intersect, Midpoint, and OrthogonalLine, the construction of an ellipse and its related elements is illustrated. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Ellipse(foci_1, foci_2, C) → c
  2. Line(foci_1, foci_2) → major
  3. Intersect(c, major, 1) → vertex_1
  4. Intersect(c, major, 2) → vertex_2
  5. Midpoint(foci_1, foci_2) → center
  6. OrthogonalLine(center, major) → minor
  7. Intersect(c, minor, 2) → covertex_1
  8. Intersect(c, minor, 1) → covertex_2

AI Drawing Prompt Reference

Draw an ellipse. The ellipse has two foci, the line connecting the foci is the major axis, and the midpoint of this line is the center. From the center, draw a perpendicular line to the major axis, which intersects the ellipse at two vertices. The key objects are the foci, major axis, center, and vertices, with clear geometric relationships.
