antecedent

(=> (and (instance ?POLYGON Polygon) (geometricPart ?PART ?POLYGON)) (equal ?PART StraightLine))	Mid-level-ontology.kif 4905-4909	If a geometric figure is an instance of polygon and the geometric figure is a geometric part of another geometric figure, then the other geometric figure is equal to straight line
(=> (and (instance ?T Polygon) (equal ?T RightTriangle)) (exists (?A) (and (instance ?A TwoDimensionalAngle) (angleOfFigure ?A ?T) (equal ?A RightAngle))))	Mid-level-ontology.kif 4929-4937	If a geometric figure is an instance of polygon and the geometric figure is equal to right triangle, then there exists a two dimensional angle such that the two dimensional angle is an instance of two dimensional angle and the two dimensional angle is the angle found in the geometric figure and the two dimensional angle is equal to right angle
(=> (instance ?POLYGON Polygon) (exists (?SIDE) (and (sideOfFigure ?SIDE ?POLYGON) (geometricPart ?SIDE ?POLYGON))))	Mid-level-ontology.kif 4911-4916	If a geometric figure is an instance of polygon, then there exists an one dimensional figure such that the size of the geometric figure is the one dimensional figure and the geometric figure is a geometric part of the one dimensional figure
