This example demonstrates the quarter turn (90-degree) rotation of points, line segments, and triangles, highlighting geometric transformations and coordinate geometry. It utilizes GeoGebra commands like Polygon and Rotate, focusing on objects such as points A, B, C, and the polygon poly1, with rotation center c and transformed points A', B', C'. Ideal for high school students studying rotation properties and constructions.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Rotate(A, 270°, (2, 0)) → A'
  3. Rotate(B, 270°, (2, 0)) → B'
  4. Rotate(C, 270°, (2, 0)) → C'
  5. Polygon(A', B', C') → poly1', c', a', b'
