This example demonstrates how to construct and mirror congruent triangles to illustrate their properties. Core math concepts include triangle congruence criteria, symmetry, and geometric transformations. Construction highlights the use of GeoGebra commands like Polygon, Point, Line, Mirror, and objects such as points D, E, F, poly1, lines c, a, b. Suitable for middle school and above students to understand geometric transformations and applications of congruent triangles.

GeoGebra Commands & Parameters

  1. Polygon(D, E, F) → poly1, c, a, b
  2. Point(xAxis) → D_1
  3. Line(D_1, E_1) → d
  4. Mirror(D, d) → U
  5. Mirror(E, d) → T
  6. Mirror(F, d) → S
  7. Polygon(U, T, S) → poly1', c', a', b'
