This example demonstrates reflections in the coordinate plane. Key mathematical concepts include reflection transformations and coordinate geometry. Using GeoGebra commands such as Polygon and Mirror, the reflected shapes can be constructed. Suitable for middle school and above students to learn about reflection transformations and coordinate geometry.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c_1, a_1, b_1
  2. Textfield(rx) → inputBox1
  3. Textfield(ry) → inputBox2
  4. Mirror(A, x = rx) → A'
  5. Mirror(B, x = rx) → B'
  6. Mirror(C, x = rx) → C'
  7. Polygon(A', B', C') → poly1', c', a', b'
  8. Mirror(A, y = ry) → A'_1
  9. Mirror(B, y = ry) → B'_1
  10. Mirror(C, y = ry) → C'_1
  11. Polygon(A'_1, B'_1, C'_1) → poly1'_1, c'_1, a'_1, b'_1
  12. Mirror(A, y = x) → A'_2
  13. Mirror(B, y = x) → B'_2
  14. Mirror(C, y = x) → C'_2
  15. Polygon(A'_2, B'_2, C'_2) → poly1'_2, c'_2, a'_2, b'_2
