CircleFunctionTrigonometryGeometric Construction
In collections Angles Created by Secants and Tangents
This example demonstrates the intersections and relationships among multiple circles. It involves core mathematical concepts such as circles, intersections, exponential functions, spheres, perimeter, median value, and stochastic processes. The construction uses GeoGebra commands like Circle, Tangent, Point, Line, Angle, and Segment. It is suitable for high school and above students to understand the interaction between geometric constructions and function graphs.

GeoGebra Commands & Parameters

  1. Circle(A, B) → c
  2. Tangent(B, c) → f,
  3. Point(c) → C

  5. Point(f) → D
  6. Point(f) → E
  7. Angle(C, B, D) → α
  8. Angle(E, B, C) → β
  9. Segment(C, A) → h
  10. Segment(A, B) → i
  11. Angle(C, A, B) → γ
  12. Angle(B, A, C) → δ
  13. Point(c) → F

AI Drawing Prompt Reference

Draw three circles, two of which intersect and the third is tangent to one of them. Mark the intersection points and the tangent point, then draw a line through the tangent point and one intersection point. Measure and display the angles formed by the centers of the circles, and the lengths of the segments connecting the centers to the intersection points.
