Properties & Relations  (2)

PolyhedronAngle[,{p1,p2}] is equivalent to DihedralAngle[{p1,p2},{v,w}] where v and w are vectors in adjacent faces of {p1,p2} in a polyhedron :

PolyhedronAngle[,p] is equivalent to SolidAngle[p,{u1,,ud}] where u1,,ud are vectors adjacent to the point p in a polyhedron :
