This example demonstrates the geometric representation and classification of different types of angles (acute, right, obtuse). It involves core mathematical concepts such as angle measurement, geometric classification, and Cartesian coordinate system. Construction highlights include using GeoGebra commands like Intersect, Point, Circle, Segment, Angle, and If, along with objects like points, circles, and segments. Suitable for middle school students and above learning angle classification and GeoGebra software application.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → A
  2. Point(xAxis) → B
  3. Circle(A, B) → c
  4. Point(Circle[A, 3]) → C
  5. Segment(A, C) → a
  6. Segment(A, B) → b
  7. Angle(B, A, C) → α
  8. Segment(D, E) → d
  9. Segment(D, F) → e
  10. Angle(E, D, F) → β
  11. Segment(G, H) → f
  12. Segment(I, H) → g
  13. Angle(I, H, G) → γ
  14. If(α < β, "Acute", If[α ≟ β, "Right", If[α < γ, "Obtuse", If[α ≟ γ, "Straight", "Reflex"]]]) → AngleType
