|---|---|---|
 | AccelerateForRelationalOperations | Produces a copy of the given geometry that is an accelerated geometry used to speed up relational operations. Only polyline and polygon geometries can be accelerated. If the geometry cannot be accelerated, the method returns the same input geometry. |

| Extend | Performs the extend operation on a polyline using a polyline as the extender. The output polyline will have the first and last segment of each part extended to the extender if the segments can be interpolated to intersect the extender. In the case that the segments can be extended to multiple segments of the extender, the shortest extension is chosen. Only end points for parts that are not shared by the end points of other parts will be extended. If the polyline cannot be extended by the input extender, then a null will be returned. |

| GeodesicEllipse | The function returns a piecewise approximation of a geodesic ellipse (or geodesic circle, if semiAxis1Length = semiAxis2Length). Constructs a geodesic ellipse centered on the specified point. If this method is used to generate a polygon or a polyline, the result may have more than one part, depending on the size of the ellipse and its position relative to the horizon of the coordinate system. When the method generates a polyline or a multipoint, the result vertices lie on the boundary of the ellipse. When a polygon is generated, the interior of the polygon is the interior of the ellipse, however the boundary of the polygon may contain segments from the spatial reference horizon, or from the GCS extent. |
| GeodesicLength | Overloaded. |
| GeodesicSector | The function returns a piecewise approximation of a geodesic ellipse (or geodesic circle, if SemiAxis1Length = SemiAxis2Length). Constructs a geodesic ellipse centered on the specified point. If this method is used to generate a polygon or a polyline, the result may have more than one part, depending on the size of the sector and its position relative to the horizon of the coordinate system. When the method generates a polyline or a multipoint, the result vertices lie on the boundary of the ellipse. When a polygon is generated, the interior of the polygon is the interior of the sector, however the boundary of the polygon may contain segments from the spatial reference horizon, or from the GCS extent. |

| NearestVertex | Finds the nearest vertex in the geometry to a specified point. |
| NormalizeCentralMeridian | Folds the geometry into a range of 360 degrees. This may be necessary when wrap around is enabled on the map. If geometry is an Envelope then a Polygon will be returned unless the Envelope is empty in which case an empty Envelope will be returned. |
| Offset | Returns offset version of the input geometry. The offset operation creates a geometry that is a constant distance from an input polyline or polygon. It is similar to buffering, but produces a one sided result. If offset distance > 0, then the offset geometry is constructed to the right of the oriented input geometry, otherwise it is constructed to the left. For a simple polygon, the orientation of outer rings is clockwise and for inner rings it is counter clockwise. So the "right side" of a simple polygon is always its inside. The bevelRatio is multiplied by the offset distance and the result determines how far a mitered offset intersection can be from the input curve before it is beveled. |
