A monotone rectilinear polygon is a monotone polygon which is also rectilinear. A T-square is a fractal generated from a sequence of rectilinear polygons with interesting properties. Algorithmic problems involving rectilinear polygons
In the visual arts, shape is a flat, enclosed area of an artwork created through lines, textures, or colours, or an area enclosed by other shapes, such as triangles, circles, and squares. [1] Likewise, a form can refer to a three-dimensional composition or object within a three-dimensional composition. [2]
A shape is a two-dimensional design encased by lines to signify its height and width structure, and can have different values of color used within it to make it appear three-dimensional. [2] [4] In animation, shapes are used to give a character a distinct personality and features, with the animator manipulating the shapes to provide new life. [1]
Geometrically K 3 forms the edge set of a triangle, K 4 a tetrahedron, etc. The Császár polyhedron, a nonconvex polyhedron with the topology of a torus, has the complete graph K 7 as its skeleton. [15] Every neighborly polytope in four or more dimensions also has a complete skeleton. K 1 through K 4 are all planar graphs.
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.
The question about how many vertices/watchmen/guards were needed, was posed to Chvátal by Victor Klee in 1973. [1] Chvátal proved it shortly thereafter. [2] Chvátal's proof was later simplified by Steve Fisk, via a 3-coloring argument. [3] Chvátal has a more geometrical approach, whereas Fisk uses well-known results from Graph theory.
The taxicab distance is also sometimes known as rectilinear distance or L 1 distance (see L p space). [1] This geometry has been used in regression analysis since the 18th century, and is often referred to as LASSO. Its geometric interpretation dates to non-Euclidean geometry of the 19th century and is due to Hermann Minkowski.
The T-puzzle, a T shape can be assembled with the four pieces on the left. The T puzzle is a tiling puzzle consisting of four polygonal shapes which can be put together to form a capital T. The four pieces are usually one isosceles right triangle , two right trapezoids and an irregular shaped pentagon .
