1. Transpose(A) → m2
2. Polygon(D, E, F) → t2, f, d, e
3. Polygon(Dilate[D, a], Dilate[E, a], Dilate[F, a]) → dilatedt2, poly1_{2}, poly1_{3}, poly1_{4}
4. ApplyMatrix(m4, D) → D'_{1}
5. ApplyMatrix(m4, E) → E'_{1}
6. ApplyMatrix(m4, F) → F'_{1}
7. Polygon(D'_{1}, E'_{1}, F'_{1}) → transformedt2, f'_{1}, d'_{1}, e'_{1}
8. Dilate(E, a) → E'_{2}
9. Dilate(F, a) → F'_{2}
10. Dilate(D, a) → D'_{2}
11. Polygon(Dtranslated, Etranslated, Ftranslated) → t2Translated, ftranslated, dtranslated, etranslated
