DihedralAngle

DihedralAngle[{p1,p2},{v,w}]

gives the angle between two half-planes bounded by the line through p1 and p2 and extended in the direction v and w.

Details

  • DihedralAngle is also known as face angle or torsion angle.
  • DihedralAngle[{p1,p2},{v,w}] is the length of the arc of the unit circle Circle[p1] on the plane with normal p2-p1 and delimited by the halfplanes HalfPlane[{p1,p2},v] and HalfPlane[{p1,p2},w].
