  3. Segment(C, D) → c
  4. Segment(D, A) → d
  5. Segment(E, F) → e
  6. Segment(F, G) → f
  7. Segment(G, H) → g
  8. Segment(H, E) → h
  9. Segment(I, J) → i
  10. Segment(J, K) → j
  11. Segment(K, I) → k
  12. Polygon(A, B, C, D) → poly1, a_1, b_1, c_1, d_1
  13. Polygon(F, G, H, E) → poly2, f_1, g_1, h_1, e_1
