TriangleTrigonometryGeometric Construction
This example uses dynamic geometry to illustrate the application of the cosine law. It involves the cosine relationship in triangles, allowing users to adjust the sides and angles to intuitively understand the cosine law. It utilizes commands such as Polygon, Angle, and Text in GeoGebra, suitable for middle and high school mathematics education.

GeoGebra Commands & Parameters

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