This example demonstrates the matrix representation of a 3D reflection. Key mathematical concepts include matrix transformations and reflections. Using GeoGebra commands such as Point, Cube, Mirror, etc., a 3D cube and its reflection surfaces are constructed. Suitable for high school mathematics education or learning 3D geometric transformations.

GeoGebra Commands & Parameters

  1. Point(Circle[I, Distance[O, I], Segment[O, I]]) → C
  2. Cube(O, I, C) → a, J, faceCDHG, faceEFGH, edgeAD, edgeAB, edgeBC, edgeCD, edgeAE, edgeDH, edgeEH, edgeEF, K, edgeBF, edgeFG, edgeCG, edgeGH, F, G, H, faceABCD, faceADHE, faceABFE, faceBCGF
  3. Mirror(a, f) → a'
  4. Mirror(J, f) → J'
  5. Mirror(K, f) → K'
  6. Mirror(I, f) → I'
  7. PointIn(f) → A

AI Drawing Prompt Reference

Draw a 3D cube and its reflection across a plane. Start by drawing a circle with center O and radius equal to the distance between O and I, then construct a cube a with vertices O, I, and C. Next, reflect cube a across plane f to get a', and reflect points I, J, and K across plane f to get I', J', and K'. Finally, draw a point A on plane f.
