# example

``` js
var findAngle = require('center-corner-vector-angle')

for (var n = 2; n <= 20; n++) {
    console.log(n + ' => ' + findAngle(n));
}
```

# methods

```
var findAngle = require('center-corner-vector-angle')
```

## var angle = findAngle(n)

Return the `angle` in radians for the regular polygon with `n` points in `n`
dimensions.

In 2 dimensions, this is the angle between the centerpoint of an equilateral
triangle and 2 of the other points, which is pi/3.
