I've been using an old copy of a program called "Geometer's Sketch Pad" to design character sheets for a tabletop game (think something like D&D). I'd like to copy over my existing work into a better program, but I don't know which ones would have the features that I've been using from GSP.
The main things I'm looking for are being able to make points, lines, geometrically accurate shapes(triangle,square, pentagon, hexagon, etc.). I also need to be able to label and color any shapes, lines, words, points, etc. Being able to export as an image file to edit in Gimp would be ideal, since I'm somewhat familiar with that program, but as long as it's possible to screen capture the finished result that's fine.
While I know that there are ways to do all of these things in Gimp, or even Paint if need be, I'm looking for software that is specialized for the features that I need. Here's an example of a picture made in GSP using all of the features I am looking for, to give an idea of how GSP works.
GSP is great software, but it was primarily intended as a learning tool for teaching geometry in middle-school and high-school, rather than as graphic design software.
