Relationships
Parents	open two dimensional figure	The class of TwoDimensionalFigures that are not ClosedTwoDimensionalFigures.
Instances	acute angle	Any TwoDimensionalAngle that has an angularMeasure that is less than 90 AngularDegrees.
	central angle	A CentralAngle is an angle whose apex (vertex) is the center of a Circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B. Central angles are subtended by an arc between those two points, and the arcLength is the central angle of a circle of radius one (measured in Radians).The central angle is also known as the arc's angular distance.[Wikipedia]
	oblique angle	Any TwoDimensionalAngle that has an angularMeasure that is greater than 90 AngularDegrees.
	right angle	Any TwoDimensionalAngle that has the angularMeasure of 90 AngularDegrees.
