(tricky one)Mitering concrete kerbs around a curved driveway

Need advice on how they get around a curved driveway. It's on a slope and curve's on both sides to the parking area right outside the house.

It's the bullnose concrete thin curbs getting installed as edging beside 60mm paving blocks. I want to come around the 2 curves with nice mitred cuts instead of just guessing it.

How do I go about calculating the measurements so I can get the exact cuts.

Might be a question for a carpenter or a roofer but thought best to put in here as it's a general building question.

lay it out with 2x1 batten overlapping. that’ll give you the length and angles of each edging .

How tight is the curve? Those edgings will look crap on anything but the slightest radius.
