If faces are all regular, the pentagonal prism is a semiregular polyhedron, more generally, a uniform polyhedron, and the third in an infinite set of prisms formed by square sides and two regular polygon caps.
Beyond the triangular bipyramid as its dual polyhedron, many other polyhedrons are related to the triangular prism. A Johnson solid is a convex polyhedron with regular faces, and this definition is sometimes omitted uniform polyhedrons such as Archimedean solids, Catalan solids, prisms and antiprisms. [12]
A familiar dispersive prism. An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light.At least one surface must be angled — elements with two parallel surfaces are not prisms.

If angle C is obtuse then for sides a, b, and c we have [4]: p.1, #74 < + <, with the left inequality approaching equality in the limit only as the apex angle of an isosceles triangle approaches 180°, and with the right inequality approaching equality only as the obtuse angle approaches 90°.
The PRISMA flow diagram, depicting the flow of information through the different phases of a systematic review. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is an evidence-based minimum set of items aimed at helping scientific authors to report a wide array of systematic reviews and meta-analyses, primarily used to assess the benefits and harms of a health care ...
Fate/kaleid liner Prisma Illya: Vow in the Snow (Japanese: 劇場版Fate/kaleid liner プリズマ☆イリヤ 雪下の誓い, Hepburn: Gekijō-ban Fate/kaleid liner Purizuma ☆ Iriya Sekka no Chikai) (also known as Oath Under Snow) is a Japanese animated fantasy action film and a prequel to the manga Fate/kaleid liner Prisma Illya by Hiroshi Hiroyama, released on August 26, 2017.

Abbe prism. The prism consists of a block of glass forming a right prism with 30°–60°–90° triangular faces. When in use, a beam of light enters face AB, is refracted and undergoes total internal reflection from face BC, and is refracted again on exiting face AC.
