Solution
By observing the line segments entering the missing rectangular portion in the main figure:
1.A segment enters at the top-left corner () and is angled towards the bottom-right.
2.A segment enters at the top-right corner () and is angled towards the bottom-left.
3.A segment enters at the middle of the left edge () and is horizontal.
4.A segment enters at the middle of the right edge () and is horizontal.
5.A segment enters at the bottom-left corner () and is angled towards the top-right.
6.A segment enters at the bottom-right corner () and is angled towards the top-left.
