What are the three angles used to evaluate pronation vs. supination in the DP view?

Talocalcaneal, cuboid abduction, and forefoot adductus angles.

What are the three angles used to evaluate pronation vs. supination in the lateral view?

Talar declination, first metatarsal declination, and calcaneal inclination angles.

Why is it useful to determine whether the foot is pronated or supinated?
Foot position can have a profound effect on the form of bones. One needs to be able to predict these appearances, and not misinterpret "odd-appearing" bone forms as pathology.
