## triangleGrid

Creates a grid of triangular polygons.

### Parameters

*   `bbox` **[BBox][1]** extent of grid in \[minX, minY, maxX, maxY] order
*   `cellSide` **[number][2]** dimension of each grid cell.  Two triangles are created in each cell.
*   `options` **[Object][3]** Optional parameters (optional, default `{}`)

    *   `options.units` **Units** used in calculating cellSide.  Supports all valid Turf [Units][4] (optional, default `'kilometers'`)
    *   `options.mask` **[Feature][5]<[Polygon][6]>?** if passed a Polygon or MultiPolygon, the grid Points will be created only inside it
    *   `options.properties` **[Object][3]** passed to each point of the grid (optional, default `{}`)

### Examples

```javascript
var bbox = [-95, 30 ,-85, 40];
var cellSide = 50;
var options = {units: 'miles'};

var triangleGrid = turf.triangleGrid(bbox, cellSide, options);

//addToMap
var addToMap = [triangleGrid];
```

Returns **[FeatureCollection][7]<[Polygon][6]>** grid of polygons
