 If the ArcObject component throws an exception.public void project(ISpatialReference newReferenceSystem) throws IOException, AutomationException
To Project, the geometry needs to have a Spatial Reference set, and not have an UnknownCoordinateSystem. The new spatial reference system passed to the method defines the output coordinate system. If either spatial reference is Unknown, the coordinates are not changed. The Z and measure values are not changed by the Project method.
A geometry is not densified before it is projected. This can lead to the output geometries not reflecting the 'true' shape in the new coordinate system. A straight line in one coordinate system is not necessarily a straight line in a different coordinate system. Use IGeometry2::ProjectEx if you want to densify the geometries while they are projected.
The Project method must be applied on highlevel geometries only. HighLevel geometries are point, multipoint, polyline and polygon. To use this method with lowlevel geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into highlevel geometry types.
If a geometry is projected to a projected coordinate system that can't represent the geographic area where the geometry is located (or if trying to move an xy coordinate from outside the projected coordinate system back into geographic), the geometry will be set to empty.
Note: This method can only be called upon the top level geometries (Points, Multipoints, Polylines and Polygons). If the from/to spatial references have different geographic coordinate systems, the Project method looks for a GeoTransformationsOperationSet. If the set of Geotransformations is present in memory, Project will use it to perform a geographic/datum Transformation. To use a specific geotransformation, use the IGeometry2::ProjectEx method.

When applying the AddGeometry method give either the before or after index and not both. Adding a Geometry to the collection as the first one is done by setting the before index as 0.
The spatial reference of the GeometryCollection is transferred (objects projected if necessary) to any objects added to it. However the spatial reference of the added geometry is not transferred to the GeometryCollection. Always make sure to set the spatial reference on the object GeometryCollection prior to add other geometries to it to avoid creating invalid geometry. For example, adding geometry objects to a GeometryBag that doesn't have a welldefined spatial reference will set an undefined spatial reference to all the objects added to the bag. Using this GeometryBag may cause unexpected behavior with the ITopologicalOperator::ConstructUnion method.

 If the ArcObject component throws an exception.public boolean contains(IGeometry other) throws IOException, AutomationException
The base geometry contains the comparison geometry (other) if the comparison geometry is a subset of the base geometry and the intersection of their interiors is not empty. Therefore a polygon does not contain any part of its 1D boundary. Contains is the opposite operator of Within.
Only geometries that support the IRelationalOperator interface can be used as input geometries.
If geometry1 Contains geometry2, then geometry2 is Within geometry1.
An empty geometry does not contain another geometry. On the other hand, an empty geometry is contained in another geometry, unless the other geometry is empty.
Contains examples. Only "true" relationships are showed in this picture.

Relation allows a general relation defined using the Shape Comparison Language to be determined between two input geometries. The Shape Comparison Language is based on the CalculusBased Method (CBM), as described and defined by Clementini and Felice, but has some extensions specific to working with vertexbased geometries and is fully described in the Technical Documents section of the ArcObjects Developer Help. Please refer to the Shape Comparison Language documentation for proper syntax and available functionality.
Note that at the current release, Relation only operates with straight lines.

 If the ArcObject component throws an exception.public boolean isSimple() throws IOException, AutomationException
Returns TRUE if the geometry is topologically Simple (refer to the discussion for the Simplify method). If the geometry is not Simple, it may be necessary to call Simplify to enforce topological consistency. Editing a geometry can change the IsSimple state of the geometry.
ITopologicalOperator methods must be applied on highlevel geometries only. HighLevel geometries are point, multipoint, polyline and polygon. To use this method with lowlevel geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into highlevel geometries types.
The xy cluster tolerance value of the geometry's associated spatial reference is used by this method. If the goal of this method is to determine if a geometry can be persisted in an sde (or other integerbased) layer without alteration, you may wish to use the minimum xy cluster tolerance value (ISpatialReferenceTolerance::SetMinimumXYTolerance) before applying this method (don't forget to set it back).

 If the ArcObject component throws an exception.public boolean isKnownSimple() throws IOException, AutomationException
Returns TRUE when the geometry is aware that it is Simple. IsKnownSimple may return FALSE even if the geometry is simple as long as the geometry is not aware of its IsSimple state. Calling either IsSimple or Simplify makes the IsSimple state known to the geometry. Topologically altering the geometry makes the IsKnownSimple state FALSE until the IsSimple state is again checked.
Here is the status of the IsKnownSimple flag in some common situations:
IsKnownSimple = 'False'
 A nonempty newly created geometry. For example, creating a polygon using IPointCollection sets the flag IsKnownSimple = 'false' on that geometry.
 Geometry after projection (IGeometry::Project )
 Geometry after generalization (IPolycurve::Generalize ) or smoothing(IPolycurve::Smooth )

Simplify permanently alters the input geometry, making its definition "topologically legal" with respect to its geometry type:
The XY tolerance property of the geometry's associated spatial reference is used during the simplify operation for polylines and polygons.
This method first looks at the ITopologicalOperator::IsKnownSimple flag before starting processing. If the flag is 'true' then operation is interrupted and the geometry is considered simple. If the flag is 'false' then the geometry consistency is checked and the geometry is updated as needed.

AutomationException
 If the ArcObject component throws an exception.public void scale(IPoint origin, double sx, double sy) throws IOException, AutomationException
Stretches the Geometry a factor of sX along the XAxis and a factor of sY along the YAxis (where sX is the ratio of Old Width to New Width, and sY is the ratio of Old Height to New Height). The Origin point is the reference Point from which the transformation is performed (Regardless of the location of the Origin point, the Geometry resulting from the transformation is the same, except for a positional offset). The Origin is the only point in the transformation guaranted to remain in the same location after the transformation is complete.
Note: Caution must be taken when scaling a CircularArc or a geometry containing CircularArc segments. Unless Abs(ScaleX) = Abs(ScaleY), the resulting CircularArcs will not retain the characteristics of the original geometry (since they remain CircularArcs).
