This example demonstrates the properties of two tangent lines drawn from an external point to a circle, focusing on intersection points and distance measurements. Key math concepts include circle, tangent line, intersection, and distance calculation. GeoGebra commands used are Circle, Tangent, Intersect, and Distance. Suitable for high school geometry instruction and exploration.

GeoGebra Commands & Parameters

  1. Circle(O, 5) → c
  2. Tangent(C, c) → a, b
  3. Intersect(c, b) → A
  4. Intersect(c, a) → B
  5. Distance(C, A) → distanceBC
  6. Distance(C, B) → distanceBD
