## Parabolic curve with straight lines to create a self-contained shape

Honestly I don’t know if this is more of a maths question than a design one, but: I have been asked to redraw this shape:

So I have the letter 0 hand written. Now I want it a bit fatter. But I don’t know how to scale every anchor point handle and keeping it’s symmetry. The only solution I could find is to do each handle one by one but I am afraid that it loses it’s symmetry.

In Inkscape, I can convert a corner node directly to a cusp (turning the lines on each side into bezier curves with the curve handles on the node being asymmetrical.) when you do this, Inkscape preserves the original angle of the lines, which is handy if you only want one side to be curved, or you only want to introduce a slight curve.

I have done this using Designer Persona. However, I can’t see how I could colour the space between the curves that are not enclosed without having to re-do the shape and enclose it.

(This is my first question here so apologies in advance if I break any rule. I have seen a question on how to align an object relative to nodes here, but I haven’t found how to align a node with respect to another object.)

Can you please explain how to convert one Bézier curve to several straight lines?

New here, so let me know if I do something wrong!

For a map outline which has large number of nodes concentrated in a small area , `is it possible to undo only the last drawn node`

in case of an error?

The image below is the result of the intersection between a path and some bezier lines. As you can see, the lines go beyond the path behind them.
