- startAngle: - 39.056642 (from centre to point A)
- note that most geodetic tools will return a true bearing (such as 320.943358 deg in this case). However, the actual statAngle value used in the ArcByCenterPoint will need to take into consideration the CRS type (left-handed in this case) and the arc direction (clockwose clockwise in this case). Therefore, the startAngle value needs to be smaller than the endAngle value. For this purpose, the startAngle is calculated by subtracting the bearing from 360.
