Description


 * Good... you missed explainig how you found the description 3pts [[image:pumpkin2.gif]]**

To definite a polygon is necessary identify the numbers and magnitude of sides, angles apexes, diagonals, apothegm (if is a regular polygon), and calculate its area and perimeter.
 * __ Description: __**

The word polygon origin’s come of ancient Greek, πολύγωνον (polygōnon) , of poly (much) and gonos (angles). Exist too regular and irregular polygons. This will be definited in ** Classification **!!

=Assignment= [|__http://en.wikipedia.org/wiki/Fractal__] 1. There is a definition of fractals there. Please identify it and identify its components. 2. There is a description there, please identify it and tell me how you found it. What helped you when locating it.
 * I. In the text you will find when you click the link below, extract the first two paragraphs and please find all the characteristics of fractals and underline them. Also find the adjectives and circle them.Be careful ! ! ! **

From Wikipedia, the free encyclopedia Jump to: [|navigation], [|search]     The [|Mandelbrot set] is a ** famous **example of a fractal A **fractal ** is "a ** rough ** or ** fragmented geometric shape ** that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole," [|[1]] a property called self-similarity. Roots of mathematical interest on fractals can be traced back to the late 19th Century; however, the term "fractal" was coined by Benoît Mandelbrot in 1975 and was derived from the Latin // fractus // meaning "** broken **" or "** fractured .**" A ** mathematical **fractal is based on an equation that undergoes iteration, a form of feedback based on recursion. [2] A fractal often has the following features: [|[3]] Because they appear similar at all levels of magnification, fractals are often considered to be infinitely ** complex ** (in informal terms). Natural objects that approximate fractals to a degree include clouds, mountain ranges, lightning bolts, coastlines, snow flakes, various vegetables (cauliflower and broccoli), and animal coloration patterns. However, not all self-similar objects are fractals—for example, the **real** line (a ** straight ** Euclidean line ) is formally self-similar but fails to have other fractal characteristics; for instance, it is regular enough to be described in Euclidean terms. Images of fractals can be created using fractal-generating software. Images produced by such software are normally referred to as being fractals even if they do not have the above characteristics, as it is possible to zoom into a region of the image that does not exhibit any fractal properties.

2.- The description is all the features of fractal. That are separated by points, and are 5 !! I can recognize it because have many details that help to explain the meaning of fractal.
