1. Line(A, B) → a
2. Sequence((deltax * i, b + deltay * i), i, -20, 20) → L
3. Sequence(Segment[A + (deltax * (i + 1), deltay * i), A + (deltax * (i + 1), deltay * (i + 1))], i, -10, 10) → list1
4. Sequence(Segment[A + (deltax * i, deltay * i), A + (deltax * (i + 1), deltay * i)], i, -10, 10) → list2
5. Point(list1) → C
6. Polygon(A, B, C) → poly1, c, Rise, Run
7. Slope(a) → m_1
8. OrthogonalLine(B, a) → d
9. Slope(d) → m_2
10. Polygon(B, D, E) → poly2, e, b_1, d_1
11. Segment(B, D) → Run_2
12. Segment(D, E) → Rise_2
