Answer:
The bicondylar angle positions the center of mass above the base of support during the single-support phase of bipedal locomotion.
A. True
Explanation:
The bicondylar angle is the functional angle between the diaphysis of the femur, perpendicular to the intercondylar plane. Very unique to humans, this angle places the knee and the foot under the body's center of gravity during a single support phase of locomotion or gait. With hip joints set lateral to the body's midline, the bicondylar angle aligns the lower limb with the center of gravity, thereby facilitating human movement.
