Description

When creating a polygon, I often want to be able to create it with a radius based on the middle segment. For example, with hexagons:

What the radius currently sets

What I want to set as the radius

I don't know how this should be implemented. Should it be a toggle? It could be a simple custom component with a relatively simple trigonomery node also. Should it be implemented directly within the editor?

I currently don't realize what is the scope of these nodes. Should they be general? Should the provide the bare minimum to be composable into any wanted node?

Contributor guide

Research direction
Investigate the polygon node implementation and add an option to use inner radius instead of outer radius. Consider adding a toggle or a custom node. The trigonometry involves using the apothem (inner radius) formula: inner = outer * cos(π/n).
