- A polygon is a  closed plane figure made of three or more straight line segments. The term originated from ancient Greek polygonon, which breaks down to polus (many) and gonia (angle). A polygon is a closed plane figure made of three or more straight line segments.

- It is thought to have diverged from the Proto-Sinaitic alphabet as early as 1300 BCE, and a developing form appeared in Babylonia and near Elath of the Gulf of Aqaba around the 8th/7th centuries BCE.

- A regular polygon is a polygon with all angles and all sides congruent, or equal. Here are some regular polygons. We can use a formula to find the sum of the interior angles of any polygon. In this formula, the letter n stands for the number of sides, or angles, that the polygon has. sum of angles = (n – 2)180°. Let's use the formula to find the sum of the interior angles of a triangle. Substitute 3 for n. We find that the sum is 180 degrees.

The History of Pita Bread: Practical & Healthy for Millennia History of Pitas. From what archeologists can determine, the pita originated with peoples west of the Mediterranean. It is not perfectly clear if it was the Amorites or the Bedouins were the inventors. Both the farming and desert society respectively adopted pitas as their own.

What is an eight-sided polygon called? A shape with many sides is called a polygon. And because math was developed a lot during the greek's time, naming things such as shapes come from the greeks. Triangles (3 sided shapes) only have three angles while Rectangles only have 4 (squares are rectangles). For others, the prefix is penta (5) hexa(6), hepta (7) Octa (8), Nona (9) Deca (10) and so on... So a polygon with 8 sides is called an octagon.

- However, contact with the Americas does not necessarily mean that the Polynesians originated there and the prevailing theory of the late 1800s and early l900s was that the Polynesians were actually an Indo-European group who came to the Pacific via India.

- These shapes are all examples of polyhedra. A three-dimensional shape whose faces are polygons is known as a polyhedron. This term comes from the Greek words poly, which means many, and hedron, which means face.. So, quite literally, a polyhedron is a three-dimensional object with many faces.

What is a Polygon? - Definition, Shapes & Angles A special class of polygon exists; it happens for polygons whose sides are all the same length and whose angles are all the same. When this happens, the polygons are called regular polygons. A stop sign is an example of a regular polygon with eight sides.

- The reason it’s called a polygon is because the line sort of forms a plane shape with the horizontal axis as one side of the shape: Now a frequency polygon and a histogram both show the same information, but in a different way.Why would we want to draw a frequency polygon instead of a histogram? Well, the most common reason is if we want to compare two different sets of data.he reason it’s called a polygon is because the line sort of forms a plane shape with the horizontal axis as one side of the shape: Now a frequency polygon and a histogram both show the same information, but in a different way.

Frequency Polygon Or, we can say that a frequency polygon is a closed figure, which is obtained by joining the middle points of the top of rectangles of histograms. The extreme values are joined with the x-axis at the half distance of class interval from the variable of the class interval. graph which is used for understanding the shapes of distributions is known as a frequency polygon. A frequency polygon works as a histogram. It is useful for comparing the sets of data.

Polygons If a polygon's angles and sides are equal, then the polygon is called a regular polygon. If the measures of a polygon's angles or side lengths differ, then the polygon is called an irregular polygon. The shape on the left has equal sides and angles, so it is a regular polygon.f a polygon's angles and sides are equal, then the polygon is called a regular polygon.

- Even with these strict rules, the Greeks were masters of constructions. One of the easiest constructions is to form the perpendicular bisector of a line segment. They also were able to inscribe regular polygons of many different side lengths inside a circle. The first several of these side lengths are 3, 4, 5, 6, 8, 10, 12, 16, and 20. German mathematician Karl Friedrich Gauss (1777 - 1855), a great prodigy at an extremely young age, was able to determine mathematically which regular polygons were possible to construct and which were not.

- The word Geometry is derived from the Greek words gaia (geo) and metria (meter) and means earth measures. Geometry has been widely used in the field of science, engineering, computers, and art.Its origin was during the ancient civilization in Egypt, where geometry was used in their arts, astronomy, and architecture.n any case there is some sort of geometry to all chemical compounds in a sub-microscopic sort of way, and these geometric differences can often make considerable differences in the physical and chemical properties of otherwise similar or nearly identical substances.

Polygon In geometry, a polygon is a plane figure bounded by a finite sequence of line segments, a two-dimensional polytope. The line segments that make up the polygon are called sides; their intersections are called vertices. In geometry a polygon (Template:Pron-en or Template:IPAlink-en) 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).

- These segments are called its edges or sides, and the points where two edges meet are the polygon's vertices (singular: vertex) or corners. The interior of the polygon is sometimes called its body. An n-gon is a polygon with n sides; for example, a triangle is a 3-gon.

Statistics Frequency Polygons So, frequency polygon is a graph that is obtained by connecting the middle points of the intervals. We can create a frequency polygon from a histogram also. If the middle top points of the bars of the histogram are joined, a frequency polygon is formed.Frequency polygon and histogram fulfills the same purpose.raphical display of the frequency table can also be achieved through a frequency polygon. To create a. the intervals are labeled on the X-axis and the Y axis represents the height of a point in the middle of the interval.

- A crude form of math was first invented by the Sumerians in the sixth century BC. Because the Sumerians had developed a settled, agricultural civilization, they needed math as a way to measure plots of land, tax individuals, chart the sky and develop a lunar calendar.

Polygonum Polygonum is a genus in the Polygonaceae family. Common names include knotweed, knotgrass, bistort, tearthumb, mile-a-minute, smartweed and several others.

- An n-gon is a polygon with n sides. A polygon is a 2-dimensional example of the more general polytope in any number of dimensions. The basic geometrical notion of a polygon has been adapted in various ways to suit particular purposes.

- A polygon can have four sides and four angles, or many sides and many angles. A three-sided polygon is called a triangle, from the Greek word tri meaning three as in tricycle, or tripod. A three-sided polygon is called a triangle, from the Greek word tri meaning three as in tricycle, or tripod. It is very easy to find examples of triangles in the world around us, as in this street sign: A geometric drawing of a triangle is seen below. Every polygon is formed of points and segments joining the points. Each point is called a vertex (the plural for vertex is vertices), and the segments are called the sides of the polygon. The triangle below is called triangle ABC using the triangle symbol in the name, as shown. The triangle is the simplest polygon, and one of the most useful geometric figures. The triangle is also the strongest geometric figure, and is therefore used in the construction of buildings and bridges. Take a drinking straw, and cut it into three pieces.

Polygons With the exception of the triangle and quadrilateral, notice that all polygon names end with gon.. What sets regular polygon names apart from each other are their prefixes, which speak to the number of sides that they have. For instance, the prefix for the word hexagon is hexa, which essentially means six..

Properties of Polygons A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons-a polygon, by definition, is made up of straight lines.
