Two angles {dihedral angle}| are where two planes intersect. The smaller angle is angle size {inclination}. Dihedral angle lies between line in each plane perpendicular to intersection line {vertex, dihedral angle}. Dihedral angle is angle between normals to the planes. Dihedral angle measure is in radians.
