This example demonstrates the angles in a triangle. Key mathematical concepts include the sum of angles in a triangle. Using GeoGebra commands Polygon and Angle, a triangle is constructed and its three interior angles are measured. Suitable for middle school and above students to learn basic properties of triangles.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Angle(C, A, B) → α
  3. Angle(A, B, C) → β
  4. Angle(B, C, A) → γ
