  2. Prism (geometry) - Wikipedia

    en.wikipedia.org/wiki/Prism_(geometry)

    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}.

  3. Spherical trigonometry - Wikipedia

    en.wikipedia.org/wiki/Spherical_trigonometry

    Case 3: two sides and an opposite angle given (SSA). The sine rule gives C and then we have Case 7. There are either one or two solutions. Case 4: two angles and an included side given (ASA). The four-part cotangent formulae for sets (cBaC) and (BaCb) give c and b, then A follows from the sine rule. Case 5: two angles and an opposite side given ...

    en.wikipedia.org/wiki/Shoelace_formula

    Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane. [2]

  5. Triangular prism - Wikipedia

    en.wikipedia.org/wiki/Triangular_prism

    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]

    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]

  7. Prism (optics) - Wikipedia

    en.wikipedia.org/wiki/Prism_(optics)

    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.

  8. Right triangle - Wikipedia

    en.wikipedia.org/wiki/Right_triangle

    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.
