About this project
We built one focused tool: turn any standard-position angle into its reference angle with context you can trust.
Reference Angle Calculator uses a light earth-tone dashboard layout so controls stay readable outdoors on a phone or indoors on a laptop.
The site is fully static with Alpine.js for the panel. That keeps hosting simple and avoids uploading your homework to a server.
Copy lives in JSON so guides can evolve without hunting through templates.
- Degrees, radians, or π rad input in one panel
- Quadrant label for the initial angle
- Live x-y diagram with initial and reference arcs
