+title: Path.circleSegment()
+---
+
+The `Path.circleSegment()` method draws a circle segment
+starting from the current endpoint of the path around the given origin with a given angle.
+
+A positive angle results in a counter-clockwise arc.
+
+A negative angle results in a clockwise arc.
+
+<Tip>
+The new endpoint of this path is the same point
+that 
+```js
+path.end().rotate(deg, origin)
+```
+would return.
+</Tip>
+
+## Signature
+
+```js
+Path path.circleSegment(deg, origin)
+```
+
+<Tip compact>This method is chainable as it returns the `Path` object</Tip>
+
+## Example
+
+<Example caption="Example of the Path.circleSegment() method">
+```js
+({ Point, points, Path, paths, part }) => {
+
+points.from = new Point(10, 20)
+points.origin = new Point(40, 0)
+
+paths.line = new Path()
