CircleOptimizationGeometric Construction
This example dynamically demonstrates the basic concepts and representations of fractions, involving core math ideas like fractions, circles, polygons, linear programming, circumcircle, LCM and GCD, centroid. It constructs graphics using commands such as Circle, Point, Segment, Append, CircleSector, Zip in GeoGebra. Suitable for middle school and above learners to understand the application of fractions combined with geometry.

GeoGebra Commands & Parameters

  1. Circle(A, 4) → c
  2. Point(c) → B
  3. Segment(A, B) → f
  4. Append(Sequence[Rotate[B, i, A], i, (360 / a)°, 359.9°, (360 / a)°], Rotate[B, 359.99°, A]) → list1
  5. CircleSector(A, B, Element[list1, b]) → d
  6. Zip(Segment[A, W], W, list1) → list2
