  1. polygon
    a closed plane figure bounded by straight sides
    In geometry a polygon (pronounced /ˈpɒlɪɡɒn/) is traditionally a plane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain).
  2. regular polygon
    a polygon with all sides and all angles equal
    A non-convex regular polygon is called a regular star polygon.
  3. interior angle
    the angle inside two adjacent sides of a polygon
    Miscellaneous
    Rectilinear: a polygon whose sides meet at right angles, i.e., all its interior angles are 90 or 270 degrees.
  4. vertex
    the highest point of something
    These segments are called its edges or sides, and the points where two edges meet are the polygon's vertices or corners.
  5. dodecagon
    a twelve-sided polygon
    Individual polygons are named (and sometimes classified) according to the number of sides, combining a Greek-derived numerical prefix with the suffix -gon, e.g. pentagon, dodecagon.
  6. pentagon
    a shape with five angles and five sides
    For example the central convex pentagon in the centre of a pentagram has density 2.
  7. heptagon
    a seven-sided polygon
    A star pentagon is known as a pentagram or pentacle.
    hexagon 6
    heptagon 7 avoid "septagon" = Latin [sept-] + Greek
    octagon 8
    enneagon (or nonagon) 9
    decagon 10
    hendecagon 11 avoid "undecagon" = Latin [un-] + Greek
    dodecagon 12 avoid "duodecagon" = Latin [duo-] + Greek
    tridecagon (or triskaidecagon) 13
    tetradecagon (or tetrakaidecagon) 14
    pentadecagon (or quindecagon or pentakaidecagon) 15
    hexadecagon (or hexakaidecagon) 16
    heptadecagon (or heptakaidecag...
  8. internal angle
    the angle inside two adjacent sides of a polygon
    Thus, he claims, the intellect is not dependent on imagination.[3]

    myriagon 10,000 See remarks on the chiliagon.
    megagon [4] 1,000,000 The internal angle of a regular megagon is 179.99964 degrees.
  9. shape
    a perceptual structure
    For example in the computer graphics (image generation) field, the term polygon has taken on a slightly altered meaning, more related to the way the shape is stored and manipulated within the computer.
