  2. Prism (geometry) - Wikipedia

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

    The volume of a prism is the product of the area of the base by the height, i.e. the distance between the two base faces (in the case of a non-right prism, note that this means the perpendicular distance). The volume is therefore: =, where B is the base area and h is the height.

  3. Triangular prism - Wikipedia

    en.wikipedia.org/wiki/Triangular_prism

    In geometry, a triangular prism or trigonal prism [1] is a prism with 2 triangular bases. If the edges pair with each triangle's vertex and if they are perpendicular to the base, it is a right triangular prism. A right triangular prism may be both semiregular and uniform. The triangular prism can be used in constructing another polyhedron.

  4. Prism graph - Wikipedia

    en.wikipedia.org/wiki/Prism_graph

    It can be generated by two elements, a rotation by an angle of 2 π /n and a single reflection, and its Cayley graph with this generating set is the prism graph. Abstractly, the group has the presentation r , f ∣ r n , f 2 , ( r f ) 2 {\displaystyle \langle r,f\mid r^{n},f^{2},(rf)^{2}\rangle } (where r is a rotation and f is a reflection or ...

  5. Trough (meteorology) - Wikipedia

    en.wikipedia.org/wiki/Trough_(meteorology)

    A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map .

  6. Triangle graph - Wikipedia

    en.wikipedia.org/wiki/Triangle_graph

    In the mathematical field of graph theory, the triangle graph is a planar undirected graph with 3 vertices and 3 edges, in the form of a triangle. [ 1 ] The triangle graph is also known as the cycle graph C 3 {\displaystyle C_{3}} and the complete graph K 3 {\displaystyle K_{3}} .

    triangle A cycle of length three in a graph. A triangle-free graph is an undirected graph that does not have any triangle subgraphs. trivial A trivial graph is a graph with 0 or 1 vertices. [16] A graph with 0 vertices is also called null graph. Turán 1. Pál Turán 2. A Turán graph is a balanced complete multipartite graph. 3.

  8. Tower of Hanoi - Wikipedia

    The nodes at the vertices of the outermost triangle represent distributions with all disks on the same peg. For h + 1 disks, take the graph of h disks and replace each small triangle with the graph for two disks. For three disks the graph is: The game graph of level 7 shows the relatedness to the Sierpiński triangle. call the pegs a, b, and c

    The Mandelbrot set, one of the most famous examples of mathematical visualization.. Mathematical phenomena can be understood and explored via visualization.Classically, this consisted of two-dimensional drawings or building three-dimensional models (particularly plaster models in the 19th and early 20th century).
