Translations:Sketcher ConstrainAngle/23/en

where:
 * Sketch is a sketch object
 * iline, iline1, iline2 are integers specifying the lines by their ordinal numbers in Sketch.
 * pointpos1, pointpos2 should be 1 for start point and 2 for end point. The choice of endpoints allows to set internal angle (or external), and it affects how the constraint is drawn on the screen.
 * geoidpoint and pointpos in AngleViaPoint are the indexes specifying the point of intersection.
 * angle is the angle value in radians. The angle is counted between tangent vectors in counterclockwise direction. Tangent vectors are pointing from start to end for the lines (or vice versa if ending point is supplied in angle between lines mode), and along counterclockwise direction for circles, arcs and ellipses. Quantity is also accepted as an angle (e.g. App.Units.Quantity('45 deg'))
