  2. Rectangle - Wikipedia

    en.wikipedia.org/wiki/Rectangle

    In Euclidean plane geometry, a rectangle is a rectilinear convex polygon or a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°); or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.

  3. Xuan tu - Wikipedia

    en.wikipedia.org/wiki/Xuan_tu

    The circle is derived from the square and the square from the rectangle (literally, the T-square or the carpenter's square). The rectangle originate from the fact that 9x9 = 81 (that is, the multiplication table or properties of numbers as such). Thus let us cut a rectangle (diagonally) and make the width 3 (units) wide and the height 4 (units ...

    English: INPUT: A 2-fat rectangle (= length/width ratio at most 2); n agents that value it as V_{n}\geq6n-8 .OUTPUT: Each agent can get a square with value \geq1 .Alternatively, each agent that values the whole as at least 4n-5 can get a 2-fat rectangle with value \geq1 . Note that a square is 2-fat.VERIFIED

  5. Four-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Four-dimensional_space

    Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.

  7. Dynamic rectangle - Wikipedia

    en.wikipedia.org/wiki/Dynamic_rectangle

    A dynamic rectangle is a right-angled, four-sided figure (a rectangle) with dynamic symmetry which, in this case, means that aspect ratio (width divided by height) is a distinguished value in dynamic symmetry, a proportioning system and natural design methodology described in Jay Hambidge's books.

  8. Golden rectangle - Wikipedia

    en.wikipedia.org/wiki/Golden_rectangle

    In geometry, a golden rectangle is a rectangle with side lengths in golden ratio +:, or ⁠:, ⁠ with ⁠ ⁠ approximately equal to 1.618 or 89/55. Golden rectangles exhibit a special form of self-similarity : if a square is added to the long side, or removed from the short side, the result is a golden rectangle as well.

  9. Rectangular cuboid - Wikipedia

    en.wikipedia.org/wiki/Rectangular_cuboid

    If a rectangular cuboid has length , width , and height , then: [5] its volume is the product of the rectangular area and its height: V = a b c . {\displaystyle V=abc.} its surface area is the sum of the area of all faces: A = 2 ( a b + a c + b c ) . {\displaystyle A=2(ab+ac+bc).}
