To calculate auxiliary points on a contour, the pocket calculator offers the following functions:
● Calculating the tangential transition between a circle sector and a straight line
● Moving a point in the plane
● Converting polar coordinates to Cartesian coordinates
● Adding the second end point of a straight line/straight line contour section given from an
angular relation
