### Coordinate Geometry calculators

## Coordinate Geometry

I mapped a lot of parcels and property lines while employed as a GIS Analyst at the Forest Preserve District of DuPage County from 2005 until 2009. Here are some Coordinate Geometry calculators that I developed in JavaScript to assist with my mapping. For each problem, fill in all the purple boxes, click "Calculate", and the solution will appear in the pink boxes.*Email Steve at*
