**Definitions**
A definition is a rethorical pattern you use to conceptualize words. Definitions usually have a term to be defined, a general class word and a characteristic or characteristics. Example A dog (term to be defined) is an animal (general class word) that barks has four legs and a tail. (characteristics)

=Description= A description is a writing form used to create an impression of an object, person, place, event, process, mechanism, etc. You can describe people, objects, animals, plants, or you can also describe how an event happened, how a mechanism operates, etcetera. In a description you find many ** adjectives ** which are the words that will characterize any thing you want to describe. __Example 1:__ In an **equilateral triangle**, all sides are of equal length. An equilateral triangle is also an equiangular polygon, i.e. all its internal angles are equal—namely, 60°; it is a regular polygon. This description was taken from the following web page: [] __Example 2:__ A polygon that is not convex is called **concave**.[|[2]] A concave polygon will always have an interior angle with a measure that is greater than 180 degrees. It is possible to cut a concave polygon into a set of convex polygons This description was taken from the following web page: []

=Assignment= Now select 5 definitions from the on-line mathematics dictionary at [], [|http://www.math.com/school/glossary/glossindex.html], [], or from any other math glossary or dictionary and copy them. Your job will be to identify: a. the term to be defined b. the general class word and c. the characteristics

1- The Absolute Value is the distance a number is from zero on the number line. For example -5 is 5 units away from zero. It would be written as |-5| 2- The Area is the number of square units needed to cover a surface 3- The Addition is the operation, or process, of calculating the sum of two numbers or quantities 4- The Hypotenuse is the side of the triangle that is opposite the right angle 5- A Rectangle is a parallelogram with four right there are in a rational number

II. **__Using your own words__**, write 1 definition about any mathematical terms. Def: The square is a parallelogram with four equal sides

** III. In the text you will find when you click the link below, extract the first paragraph and please find all the characteristics of fractals and underline them. Also find the adjectives and circle them.Be careful ! ! ! **

[] > 2. There is a description there, please identify it and tell me how you found it. What helped you when locating it.
 * 1) There is a definition of algebra there. Please identify it and identify its components.

Definition:

As a single word, "algebra" can mean: In elementary algebra: " Use of letters and symbols to represent values and their relations, especially for solving [|equations]."

In modern pure mathematics: "A major branch of mathematics which studies relations and operations."

Description :

[|Elementary algebra], often part of the curriculum in [|secondary education], introduces the concept of [|variables] representing [|numbers]. Statements based on these variables are manipulated using the rules of operations that apply to numbers, such as [|addition]. This can be done for a variety of reasons, including [|equation solving].

Algebra as a branch of [|mathematics] is much broader than elementary algebra, studying what happens, beyond arithmetics of normal numbers, when different rules of [|operations] and [|relations] are used. It leads to [|constructions] and concepts arising from them, including [|terms], [|polynomials], [|equations]. When the rules of addition and [|multiplication] are generalized, their precise definitions lead to [|algebraic structure] such as [|groups], [|rings] and [|fields], studied in the area of mathematics called [|abstract algebra].

Algebra is one of the main branches of [|pure mathematics], together with [|geometry], [|analysis], [|topology], [|combinatorics], and [|number theory].

This is a description because it explains in detail the previously defined ** YES BUT YOU FOUND IT BECAUSE OF KEY WORDS AND ADJECTIVES **

** IV. Now write a description of any mathematical word or topic. **

The angles of the triangles always are less than 180° ** THIS DEFINITION IS INCOMPLETE!! **

As soon as you have all these ready, please paste it in your wiki.
