how many triangles are on the epcot ball
Spaceship Earth (Epcot) Geometrically, Spaceship Earth is derived from the Class 2 geodesic polyhedron with frequency of division equal to 8. Each face of the polyhedron is divided into three isosceles triangles to form each point. In theory, there are 11,520 total isosceles triangles forming 3840 points. In reality, some of those triangles are partially or fully nonexistent due to supports and doors; there are actually only 11,324 silvered facets, with 954 partial or full flat triangular panels.[5]
Baseball field The dimensions of home plate are 17 inches (43 cm) across the front, 8.5 inches (22 cm) down each side, with a triangular rear of two sides of 12 inches (30 cm). The rear edges are at 45 degrees to the sides, making a point at the back.[1] The plate is white and surrounded by a black strip 3⁄4 inch (1.9 cm) in width. The plate sits entirely in "fair" territory, with the two rear edges aligned with the right and left field foul lines. The length and angle requirements for home plate mandate that it is not a regular pentagon; it is a 17 by 8.5 inches rectangle with an isosceles triangle of base 17 inches and equal sides of 12 inches attached to the back.
