CircleVectorGeometric Construction
This example demonstrates the construction of a tangent circle. It involves the properties of circles and geometric construction. Using GeoGebra commands such as Polygon, AngularBisector, and Intersect, a tangent circle can be constructed. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. AngularBisector(B, A, C) → d
  3. AngularBisector(A, B, C) → e
  4. Intersect(d, a) → E
  5. Intersect(e, b) → F
  6. Ray(A, B) → f
  7. Ray(A, C) → g
  8. Point(g) → D
  9. Point(f) → H
  10. AngularBisector(D, C, B) → h
  11. AngularBisector(H, B, C) → i
  12. Intersect(h, i) → target1
  13. OrthogonalLine(target1, g) → j
  14. Intersect(j, g) → J
  15. Circle(target1, J) → target2
