| Name | Description | |
|---|---|---|
|  | CenterPoint | Gets the center point of the arc. | 
|  | CentralAngle | Gets the central angle in radians. | 
|  | EndAngle | Gets the end angle in radians (measured from a horizontal line through the center point) defining where the arc ends. | 
|  | EndCoordinate | Gets the end point of this instance as a Coordinate2D. (Inherited from ArcGIS.Core.Geometry.Segment) | 
|  | EndPoint | Gets the end point of this instance. (Inherited from ArcGIS.Core.Geometry.Segment) | 
|  | IsCircular | Gets if this elliptic arc segment is a portion of the boundary of a 2D circle. | 
|  | IsCounterClockwise | Gets if the elliptic arc segment is counter-clockwise. | 
|  | IsCurve | Overridden. Gets if this elliptic arc segment is a curve. | 
|  | IsMinor | Gets if the elliptic arc is a minor arc. | 
|  | Length | Overridden. Gets the 2D length of this elliptic arc segment. | 
|  | MinorMajorRatio | Gets the ratio of the semi-minor to the semi-major axis. | 
|  | RotationAngle | Gets the rotation angle in radians. | 
|  | SegmentType | Overridden. Gets the segment type. This always returns SegmentType.EllipticArc. | 
|  | SemiMajorAxis | Gets the semi-major axis. The semi-major axis is the larger of the two axes, and the semi-minor axis is the smaller axis. The semi-major axis always lies on the line between 0 and PI radians. | 
|  | SemiMinorAxis | Gets the semi-minor axis. The semi-minor axis is the smaller of the two axes. The semi-minor axis always lies on the line between PI/2 and 3*PI/2 radians. | 
|  | SpatialReference | Gets the spatial reference of the instance. (Inherited from ArcGIS.Core.Geometry.Segment) | 
|  | StartAngle | Gets the start angle in radians. Start angle is adjusted to a value between -PI and +PI. | 
|  | StartCoordinate | Gets the start point of this instance as a Coordinate2D. (Inherited from ArcGIS.Core.Geometry.Segment) | 
|  | StartPoint | Gets the start point of this instance. (Inherited from ArcGIS.Core.Geometry.Segment) |
