Spherical Geometry Explorer

Published by patrick honner on

This is a simple and powerful tool for exploring some basic ideas of spherical geometry.


In addition to investigating points, lines, and line segments on the surface of sphere, you can construct triangles, antipodes, and even circles in spherical geometry!

A picture may be worth a thousand words, but a good interactive spherical geometry applet is worth a thousand well-drawn diagrams!

Your goo.gl link brings me back to this page. By any chance did you mean http://merganser.math.gvsu.edu/easel/ from my colleagues David and Will?

Thanks for the proof-reading, John! This is what I linked to:


But I’m definitely going to look into the spherical drawing program you’ve shared!
