A polygon that has twelve sides is called?
A. Decagon
B. Dodecagon
C. Nonagon
D. Octagon
Correct Answer Is Option = Dodecagon
Notes / Explanation
A polygon that has twelve sides is called a dodecagon, and this is part of the system by which shapes with straight sides are named according to how many sides they possess, a topic within the branch of mathematics that deals with shapes, known as geometry. A polygon is a flat, closed shape made up of straight sides, and each polygon is given a name according to the number of its sides, with most of these names coming from words that indicate the number in question. Thus a shape with three sides is a triangle, a shape with four sides is a quadrilateral, a shape with five sides is a pentagon, a shape with six sides is a hexagon, a shape with seven sides is a heptagon, a shape with eight sides is an octagon, a shape with nine sides is a nonagon, a shape with ten sides is a decagon, and a shape with twelve sides is a dodecagon. The name dodecagon comes from a word meaning twelve, and so a twelve-sided shape is called a dodecagon. A dodecagon has twelve sides and twelve corners, and therefore twelve angles. A regular dodecagon is one in which all twelve sides are of equal length and all twelve angles are equal, producing a symmetrical shape, while an irregular dodecagon has sides or angles that are not all equal. Because it has a fairly large number of sides, a regular dodecagon is a fairly rounded shape, coming closer in appearance to a circle than shapes with fewer sides, since, as the number of sides of a regular polygon increases, the shape comes to resemble a circle more and more closely. The dodecagon is sometimes seen in the shapes of certain coins, clocks and designs, where its twelve equal sides are used for practical or decorative purposes. The naming of polygons according to the number of their sides is a basic and useful part of geometry, allowing shapes to be described precisely, and being familiar with the names of the common polygons, from the triangle up to the dodecagon and beyond, is helpful both in the study of mathematics and as a piece of general knowledge. Questions asking for the name of a shape with a particular number of sides are commonly encountered. For PPSC and other competitive examinations, the key points to remember are that a polygon with twelve sides is called a dodecagon, that polygons are named according to the number of their sides, that a dodecagon has twelve sides, corners and angles, and that as the number of sides increases a regular polygon comes to resemble a circle more closely.
