What is the shape of a baseball field?
Answer Square……
Answer Geometrically speaking … it is a square some call it a diamond for purposes explained below. A square is a figure with four equal sides and four 90 degree corners. A diamond is a square who’s long corner-to-corner axis is arranged perpendicular to the frame of reference (in this case, home plate). The baseball diamond is a square 90 feet on each side, and a 90 degree angle at each base pad. The corner at home plate culminates in the point of home plate which is closest to the catcher, thus making the entirety of home plate (and all other bases, actually) fair territory.
