This example demonstrates the effect of a 270-degree rotation. Key mathematical concepts include rotation transformation and geometric construction. Using commands such as Rotate, Segment, Midpoint, CircleArc, Intersect, Point, and Vector in GeoGebra, the rotated figure can be constructed. Suitable for students at the junior high school level and above to learn about geometric transformations.

GeoGebra Commands & Parameters

  1. Rotate(A, 270°, O) → A'
  2. Segment(O, A) → f
  3. Segment(O, B) → g
  4. Midpoint(f) → C
  5. Midpoint(g) → D
  6. CircleArc(O, C, D) → c
  7. Intersect(c, g, 1) → E
  8. Intersect(c, g, 1) → F
  9. Point(c) → G
  10. Vector(G, E) → u
