IConstructAngle Interface

Provides access to members that construct an angle using other geometries and measures. This interface is implemented by the GeometryEnvironment object.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.


ConstructAngle returns the angle formed either by three input points used to define the angle or an input line (and the implied baseline).  The constructed angle is returned in radians and is always between -Pi and Pi.


Method ConstructLine Constructs the angle between the infinite line containing the input line segment and the positive x-axis.
Method ConstructThreePoint Constructs the angle included in three points.
