This example demonstrates the Angle Addition Postulate by constructing angles α, β, and γ, and their sum angle γ, helping students understand the principle of angle addition. It uses GeoGebra commands Angle and Ray, suitable for middle school geometry.

GeoGebra Commands & Parameters

  1. Angle(A, B, C) → α
  2. Angle(A, B, D) → β
  3. Angle(D, B, C) → γ
  4. Ray(B, A) → a
  5. Ray(B, D) → b
  6. Ray(B, C) → c
