Rotate geometry/graphics at specific angle

ofirrosner

Hello
I'm using the sketch editor to create polygon/polygons etc on the map
I know i can re-select the geometry and use the sketch editor and "free-hand" to rotate and move the geometry along the map
but i want to know if there is a way rotate the geometry at some specific angle

For moving i can use GeometryEngine.MoveGeodetic() to move my geometry at specific value
but i can find an equivalent to rotate?

I already know this
guess i will have go back to good old trigonometry
