Constructors
- GeoArc2(GeoPoint2, double, double, double)
Initializes an arc running counter-clockwise from one angle to another.

Initializes an arc running from one angle to another, either way round.
Properties

Gets the centre of the circle the arc lies on.
- EndAngle
Gets the angle the arc ends at, in radians, wrapped into the range from zero to a full turn.
- EndPoint
Gets the point the arc ends at.
- IsClockwise
Gets a value indicating whether the arc sweeps clockwise.
- IsValid
