TriangleTrigonometryGeometric Construction
This example demonstrates the Sine Law, which states that in any triangle, the ratio of the length of a side to the sine of its opposite angle is constant. By constructing a triangle and its sides and angles using GeoGebra commands such as Polygon, Angle, and Midpoint, one can visually understand the Sine Law. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Angle(C, A, B) → X
  3. Angle(C, B, A) → Y
  4. Angle(A, C, B) → Z
  5. Midpoint(A, C) → D
  6. Midpoint(A, B) → E
  7. Midpoint(B, C) → F
