+## polygonToLine
+
+Converts a [Polygon][1] to [(Multi)LineString][2] or [MultiPolygon][3] to a [FeatureCollection][4] of [(Multi)LineString][2].
+
+**Parameters**
+
+-   `poly` **[Feature][5]&lt;([Polygon][6] \| [MultiPolygon][7])>** Feature to convert
+-   `options` **[Object][8]** Optional parameters (optional, default `{}`)
+    -   `options.properties` **[Object][8]** translates GeoJSON properties to Feature (optional, default `{}`)
+
+**Examples**
+
+```javascript
+var poly = turf.polygon([[[125, -30], [145, -30], [145, -20], [125, -20], [125, -30]]]);
+
+var line = turf.polygonToLine(poly);
+
+//addToMap
+var addToMap = [line];
+```
+
+Returns **([FeatureCollection][9] \| [Feature][5]&lt;([LineString][10] | MultiLinestring)>)** converted (Multi)Polygon to (Multi)LineString
