This example demonstrates how to rotate an isosceles triangle around a point. The core math concepts involved include congruence, rotation, and geometric transformations. Construction highlights the use of GeoGebra commands and objects such as Circle, Angle, Polygon, Vector, and Rotate. Suitable for middle school students learning geometric transformations.

GeoGebra Commands & Parameters

  1. Circle(G, 2) → c
  2. Angle(I, G, F) → angle_1
  3. Polygon({A, B, C}) → triangle
  4. Vector(G, F) → u
  5. Vector(G, I) → v
  6. Rotate(triangle, angle°, O) → triangle'
  7. Rotate(C, angle°, O) → C'
  8. Rotate(B, angle°, O) → B'
  9. Rotate(A, angle°, O) → A'
