Sigma KEE - relativeAngle
relativeAngle

appearance as argument number 1
-------------------------


(documentation relativeAngle EnglishLanguage "(relativeAngle ?O1 ?O2 ?MEASURE) means that the two-dimensional geometric angle formed by ?O1 and ?O2 has ?MEASURE.") Merge.kif 17615-17616
(documentation relativeAngle EnglishLanguage "One end of an object, which is the smallest part of an object that is the longest distance from the other end.") Merge.kif 17674-17676
(domain relativeAngle 1 Object) Merge.kif 17612-17612 The number 1 argument of relative angle is an instance of object
(domain relativeAngle 2 Object) Merge.kif 17613-17613 The number 2 argument of relative angle is an instance of object
(domain relativeAngle 3 RealNumber) Merge.kif 17614-17614 The number 3 argument of relative angle is an instance of real number
