The correct answer is dihedral.

Key Points

The angle formed by two intersecting planes or half-planes is known as a dihedral angle.
It is the clockwise angle between half-planes in chemistry that passes across two sets of three atoms that share two atoms.
It is described in solid geometry as the union of a line and two half-planes that share this line's edge.

Additional Information

Spline:
- The pitch diameter's angle with the involute curve and a tangent point on the base diameter make up a spline's pressure angle.
Offset:
- It refers to striking a balance between two forces so that there is little variation between them.
Polar:
- It is the counterclockwise angle from the x-axis at which a point in the negetive plane lies.
