  2. Triangular prism - Wikipedia

    en.wikipedia.org/wiki/Triangular_prism

    A triangular prism has 6 vertices, 9 edges, and 5 faces. Every prism has 2 congruent faces known as its bases, and the bases of a triangular prism are triangles.The triangle has 3 vertices, each of which pairs with another triangle's vertex, making up another 3 edges.

  4. Prism (geometry) - Wikipedia

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

    Right Prism. A right prism is a prism in which the joining edges and faces are perpendicular to the base faces. [5] This applies if and only if all the joining faces are rectangular. The dual of a right n-prism is a right n-bipyramid. A right prism (with rectangular sides) with regular n-gon bases has Schläfli symbol { }×{n}.

  5. Tetrahedron - Wikipedia

    en.wikipedia.org/wiki/Tetrahedron

    A negative value of the determinant means that a tetrahedron cannot be constructed with the given distances. This formula, sometimes called Tartaglia's formula, is essentially due to the painter Piero della Francesca in the 15th century, as a three-dimensional analogue of the 1st century Heron's formula for the area of a triangle. [20]

    The same formula holds for any three-dimensional objects, except that each should be the volume of , rather than its area. It also holds for any subset of R d , {\displaystyle \mathbb {R} ^{d},} for any dimension d , {\displaystyle d,} with the areas replaced by the d {\displaystyle d} -dimensional measures of the parts.

  7. Heron's formula - Wikipedia

    en.wikipedia.org/wiki/Heron's_formula

    Heron's formula can be obtained from Brahmagupta's formula or Bretschneider's formula by setting one of the sides of the quadrilateral to zero. Brahmagupta's formula gives the area ⁠ K {\displaystyle K} ⁠ of a cyclic quadrilateral whose sides have lengths ⁠ a , {\displaystyle a,} ⁠ ⁠ b , {\displaystyle b,} ⁠ ⁠ c , {\displaystyle c ...

    en.wikipedia.org/wiki/Talk:Triangular_prism

    The formula for an isosceles triangular base in the prism is: A1×2+A2×2+A3. The formula for a scalene triangular base in the prism is: A1×2+A2+A3+A4. To get the volume of a triangular prism you need to find the base area of the triangle(0.5*bh) and the length of the prism. The General formula that is commonly used is: Base Area*length or 0.5 ...
