Final answer:
A Colles fracture angulates in the dorsal direction, while a Smith fracture angulates in the volar direction.
Step-by-step explanation:
A Colles fracture angulates in the dorsal direction. This means that the broken end of the distal radius moves towards the back of the hand. On the other hand, a Smith fracture angulates in the volar direction. This means that the broken end of the distal radius moves towards the palm side of the hand.
