Sorry, I can't understand what you require.
Can you provide a better explanation.

Hi Kerry. Thanks for your helpful mind.

I will put it simple. I have two parallel arcs.

1. A line to be drawn from the start of the inner arc to crown of the inner arc (say line A)
    and from end of inner arc to the crown of inner arc (say line B)
2. These lines will intersect with the outer arc at some point.
3.  From that intersection of line A. a new line to be drawn tangent to the inner arc but
    extending towards the outer arc.
4. This will repeat till the new line will intersect with the line B.

I know its bit difficult to understand. Please refer the attached image for better understanding.

Green lines in the image are line A & Line B

Thanks
