Assertion: polyhedron's vertex | /r/HasProperty | congruent
Facets:
value: within a single symmetry orbit
type: LOCATION
Source sentences:
text: It follows that all vertices are congruent, and the polyhedron has a high degree of reflectional and rotational symmetry.
text: It follows that all vertices are congruent.
text: Where there is only one kind of peak, or vertex, in a stellation (i.e. all vertices are congruent within a single symmetry orbit), the stellation is monoacral.
text: Where there is only one kind of peak, or vertex, in a stellation (i.e. all vertices are congruent within a single symmetry orbit), the stellation is monoacral.
text: Added constraint is that vertices must be congruent and edges equal in length.
