Polygon Shape Names 1-12
In geometry, a polygon is a closed two-dimensional figure with straight sides. Polygons come in many shapes and sizes, but in this article we will focus on the names and characteristics of polygons with 1-12 sides. Understanding the names of polygons can help in identifying and classifying shapes, as well as in solving geometry problems.
1. Monogon
A monogon, also known as a henagon, is a polygon with just one side. It is not considered a polygon in the traditional sense, as it does not meet the requirement of having at least three sides. In fact, a monogon cannot exist in Euclidean geometry, which is the study of flat shapes and spaces.
2. Digon
A digon, also known as a bigon, is a polygon with two sides. It is another shape that does not exist in Euclidean geometry, as it cannot form a closed figure. However, digons can be found in other types of geometry, such as hyperbolic geometry.
3. Triangle
A triangle is a polygon with three sides. It is one of the most basic and commonly studied polygons in geometry. Triangles can be classified by their angles (acute, right, or obtuse) and by the length of their sides (scalene, isosceles, or equilateral).
4. Quadrilateral
A quadrilateral is a polygon with four sides. The most common types of quadrilaterals are squares, rectangles, parallelograms, and trapezoids. Quadrilaterals can also be classified by their angles (convex or concave) and by the length of their sides (rhombus or kite).
5. Pentagon
A pentagon is a polygon with five sides. It is a common shape in nature and can be found in the structure of many plants and animals. The most famous pentagon is the Pentagon building in Washington, D.C., which is the headquarters of the United States Department of Defense.
6. Hexagon
A hexagon is a polygon with six sides. It is a common shape in geometry and can be found in many everyday objects, such as bolts and nuts. Hexagons are also found in nature, such as in the honeycomb structure of beehives.
7. Heptagon
A heptagon, also known as a septagon, is a polygon with seven sides. It is a less common shape in geometry and is not as well-known as some of the other polygons. Heptagons can be found in some types of crystals and in some ancient architectural designs.
8. Octagon
An octagon is a polygon with eight sides. It is a popular shape in architecture and can be seen in many buildings, such as the stop sign. Octagons can also be found in nature, such as in some types of starfish.
9. Nonagon
A nonagon is a polygon with nine sides. It is a less common shape in geometry and is not as well-known as some of the other polygons. Nonagons can be found in some types of crystals and in some ancient architectural designs.
10. Decagon
A decagon is a polygon with ten sides. It is a popular shape in geometry and can be seen in many everyday objects, such as the shape of a drum. Decagons can also be found in nature, such as in some types of starfish.
11. Hendecagon
A hendecagon, also known as an undecagon, is a polygon with eleven sides. It is a less common shape in geometry and is not as well-known as some of the other polygons. Hendecagons can be found in some types of crystals and in some ancient architectural designs.
12. Dodecagon
A dodecagon is a polygon with twelve sides. It is a popular shape in geometry and can be seen in many everyday objects, such as a clock face. Dodecagons can also be found in nature, such as in some types of starfish.
Understanding the names and characteristics of polygons can be helpful in many areas of life, from architecture to engineering to art. By learning about these shapes, we can better understand the world around us and appreciate the beauty and complexity of geometry.
So, next time you come across a polygon, take a moment to appreciate its shape and the name it carries.
