Final answer:
The shape of the face where the jaw is the widest part is called the angle of the mandible.
Step-by-step explanation:
The shape of the face where the jaw is the widest part is considered to be the angle of the mandible. The mandible forms the lower jaw and is the only movable bone of the skull. It consists of paired right and left bones that fuse together during the first year to form the single U-shaped mandible of the adult skull. The angle of the mandible is where the body and ramus of the mandible come together (Figure 7.15).
