+## lineArc
+
+Creates a circular arc, of a circle of the given radius and center point, between bearing1 and bearing2;
+0 bearing is North of center point, positive clockwise.
+
+**Parameters**
+
+-   `center` **[Coord][1]** center point
+-   `radius` **[number][2]** radius of the circle
+-   `bearing1` **[number][2]** angle, in decimal degrees, of the first radius of the arc
+-   `bearing2` **[number][2]** angle, in decimal degrees, of the second radius of the arc
+-   `options` **[Object][3]** Optional parameters (optional, default `{}`)
+    -   `options.steps` **[number][2]** number of steps (optional, default `64`)
+    -   `options.units` **[string][4]** miles, kilometers, degrees, or radians (optional, default `'kilometers'`)
+
+**Examples**
+
+```javascript
+var center = turf.point([-75, 40]);
+var radius = 5;
+var bearing1 = 25;
+var bearing2 = 47;
+
+var arc = turf.lineArc(center, radius, bearing1, bearing2);
+
+//addToMap
+var addToMap = [center, arc]
+```
+
+Returns **[Feature][5]&lt;[LineString][6]>** line arc
