Relating to or positioned opposite to the feet; in mathematics or science, referring to points or structures that are diametrically opposed.
From Greek 'anti' (opposite/against) + Latin 'pedalis' (relating to feet, from 'pes' meaning foot). The term literally means 'opposite the foot' and is used in geometry and anatomy.
In geometry, 'antipodal' points are on opposite sides of a sphere, but 'antipedal' has a more specific meaning in triangle geometry—it's a technical term that even many math teachers have never heard of!
