High Quality Content by WIKIPEDIA articles! In geometry, an n-sided antiprism is a polyhedron composed of two parallel copies of some particular n- sided polygon, connected by an alternating band of triangles. Antiprisms are a subclass of the prismatoids.Antiprisms are similar to prisms except the bases are twisted relative to each other, and that the side faces are triangles, rather than quadrilaterals.In the case of a regular n-sided base, one usually considers the case where its copy is twisted by an angle 180°/n. Extra regularity is obtained by the line connecting the base centers being perpendicular to the base planes, making it a right antiprism. It has, apart from the base faces, 2n isosceles triangles as faces.
