A polyhedral prism is a 4-dimensional prism made from two translated polyhedra connected by 3-dimensional prism cells. A regular polyhedron {p,q} can construct the uniform polychoric prism, represented by the product {p,q}×{ }. If the polyhedron and the sides are cubes, it becomes a tesseract: {4,3}×{ } = {4,3,3}.
The octant of a sphere is a spherical triangle with three right angles.. Spherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the sides and angles of spherical triangles, traditionally expressed using trigonometric functions.
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.
A right triangle ABC with its right angle at C, hypotenuse c, and legs a and b,. A right triangle or right-angled triangle, sometimes called an orthogonal triangle or rectangular triangle, is a triangle in which two sides are perpendicular, forming a right angle (1 ⁄ 4 turn or 90 degrees).
The Taikyoku series is a series of kata in use in several types of karate.The name Taikyoku (太極) refers to the Chinese philosophical concept of Taiji.The Taikyoku kata were developed by Yoshitaka Funakoshi and introduced by Gichin Funakoshi as a way to simplify the principles of the already simplified Pinan/Heian series.
The Golden Triangle of Jakarta (Indonesian: Segitiga Emas Jakarta), also referred to as the Medan Merdeka–Thamrin–Sudirman Axis (Indonesian: Poros Medan Merdeka–Thamrin–Sudirman) or the Sudirman–Thamrin–Kuningan Axis (Indonesian: Poros Sudirman–Thamrin–Kuningan), is a roughly triangular area in the center of Jakarta, Indonesia, extending from Central Jakarta to South Jakarta.
The Siku Quanshu Zongmu Tiyao, or the Annotated Bibliography of the Four Treasuries, [1] is an annotated catalog of the thousands of works that were considered for inclusion in the Siku Quanshu (Complete Library of the Four Treasuries). Work for the 200-chapter catalog began in 1773 and was completed in 1798. [2]
