Merge.kif 17986-17996

If an object is an instance of object and long and thin is an attribute of the object and another object is an instance of object and long and thin is an attribute of the other object and the object is connected to the other object and the object is not equal to the other object,
then there exists a real number such that the relative angle between the object and the other object is the real number
