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
