+## angle
+
+Finds the angle formed by two adjacent segments defined by 3 points. The result will be the (positive clockwise)
+angle with origin on the `startPoint-midPoint` segment, or its explementary angle if required.
+
+**Parameters**
+
+-   `startPoint` **[Coord][1]** Start Point Coordinates
+-   `midPoint` **[Coord][1]** Mid Point Coordinates
+-   `endPoint` **[Coord][1]** End Point Coordinates
+-   `options` **[Object][2]** Optional parameters (optional, default `{}`)
+    -   `options.explementary` **[boolean][3]** Returns the explementary angle instead (360 - angle) (optional, default `false`)
+    -   `options.mercator` **[boolean][3]** if calculations should be performed over Mercator or WGS84 projection (optional, default `false`)
+
+**Examples**
+
+```javascript
+turf.angle([5, 5], [5, 6], [3, 4]);
+//=45
+```
+
+Returns **[number][4]** Angle between the provided points, or its explementary.
