TriangleCircleGeometric Construction
This example demonstrates the circumcircle of a triangle. Key mathematical concepts include triangles, circles, and geometric construction. Using GeoGebra commands such as Circle, Point, and Polygon, the circumcircle of a triangle can be constructed. Suitable for middle school and above students to learn about geometric construction and properties of circles.

GeoGebra Commands & Parameters

  1. Circle(A, 3) → c
  2. Point(c) → D
  3. Point(c) → C
  4. Point(c) → B
  5. Polygon(B, C, D) → poly1, d, b, c_1
  6. Angle(B, D, C) → α
  7. Line(B, A) → g
  8. Intersect(c, g, 2) → E
  9. Segment(B, E) → a
  10. Angle(B, D, E) → β
  11. Segment(D, E) → e
  12. Segment(D, B) → f
