Description  
 
CentroidEx  
The center of gravity (centroid). 
 
 
Changed  
Indicates if a geometry has been changed (edited, projected, etc). 
 
 
Dimension  
The topological dimension of this geometry. 
 
 
Envelope  
Creates a copy of this geometry's envelope and returns it. 
 
 
GeometryType  
The type of this geometry. 
 
 
GeoNormalize  
Shifts longitudes, if need be, into a continuous range of 360 degrees. 
 
 
GeoNormalizeFromLongitude  
Normalizes longitudes into a continuous range containing the longitude. This method is obsolete. 
 
 
IsEmpty  
Indicates whether this geometry contains any points. 
 
 
Project  
Projects this geometry into a new spatial reference. 
 
 
Project5  
Same as Project, but with additional parameter projectionHint. 
 
 
ProjectEx  
Projects a geometry, optionally applies a GeoTransformation, and optionally densifies the geometry. 
 
 
ProjectEx5  
Same as ProjectEx, but with additional parameter projectionHint. 
 
 
QueryEnvelope  
Copies this geometry's envelope properties into the specified envelope. 
 
 
QueryWKSEnvelope  
Defines the specified wksenvelope to be the current extent of this geometry in the x-y plane. 
 
 
SetEmpty  
Removes all points from this geometry. 
 
 
SnapToSpatialReference  
Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system. 
 
 
SpatialReference  
The spatial reference associated with this geometry.

GeometryBag  
An ordered collection of objects that support the IGeometry interface. 
 
MultiPatch  
A collection of surface patches. 
 
Multipoint  
An ordered collection of points; optionally has measure, height and ID attributes. 
 
Point  
A two dimensional point, optionally with measure, height, and ID attributes. 
 
Polygon  
A collection of rings ordered by their containment relationship; optionally has measure, height and ID attributes. 
 
Polyline  
An ordered collection of paths; optionally has measure, height and ID attributes.
