TriangleAngleGeometric Construction
This example demonstrates the properties of equilateral triangles, which are triangles with all three sides equal and each angle measuring 60 degrees. Using GeoGebra commands such as Circle, Intersect, and Polygon, an equilateral triangle can be constructed and its angle and side length relationships explored. Suitable for middle school and above students to learn geometric construction and triangle properties.

GeoGebra Commands & Parameters

  1. Circle(A, B) → c
  2. Circle(B, A) → d
  3. Intersect(c, d, 1) → C
  4. Polygon(A, B, C) → poly1, length_2, length, length_1
  5. Angle(C, B, A) → α
  6. Angle(A, C, B) → β
  7. Angle(B, A, C) → γ
