This example demonstrates how to find the rotation center using perpendicular bisectors. Key mathematical concepts include triangles and rotation. Using GeoGebra commands such as Polygon, Rotate, Segment, and LineBisector, the rotated figure can be constructed. Suitable for students at the middle school level and above for learning geometric transformations.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Rotate(B, α, D) → B'
  3. Rotate(A, α, D) → A'
  4. Rotate(C, α, D) → C'
  5. Polygon(A', B', C') → poly2, c', a', b'
  6. Segment(A', A) → e
  7. Segment(B, B') → f
  8. LineBisector(e) → d
  9. LineBisector(f) → g

AI Drawing Prompt Reference

Draw a triangle ABC, then rotate it around point D to form a new triangle A'B'C'. Next, draw the perpendicular bisectors of line segments A'A and BB'. The intersection of these two perpendicular bisectors is the rotation center.
