 * Written Proyect : Triangles**

Definition : Triangles (term to be defined) are polygons(general class word) with three sides(characteristics)

Description: A triangle its a geometric form that consists in the area defined by three vortexs, the triangles have a lot of propertys(like the pythagorean theorem) and are very important to mathematics and other sciences like astronomy , physics , etc.

There are many types of triangles (accordng to the classification), but basically there are only three types:

EquilateralTriangles: Are the ones who their three side have equal size and all the interiors angles are of 60 grades

Isoceles Triangle : Are the ones who have two sides of equal size and have two angles of the same measure

Esclane Triangle : Are the ones who none of their sides are equal, also they three interiors angles are of diferent size.

Triangles also have a lot of properties and formulas that can be applied to them, like:

1- the sum of all interiors angles of a triangle its have to be always 180 grades 2-to know the area of a traingle we just need the size of the base, the height and do the next formula : (base x height)/2= triangle area. 3 the result of the sum of any two sides in a triangle is always grater than the other side, etc.

Classification, comparision and contrast about triangles:

Classification : Classification of Triangles.doc Classification of Triangles.doc This second version is corrected

Contrast :

Between Equilateral triangles and isosceles triangles :

Both types of triangles __haves__ three sides, and three angles

Between triangles and squares:

triangles are bydimensional polygon**S** like squares, two triangles __made__ a polygon

Comparision :

Between isosceles triangle and a scalene triangle:

The isosceles triangle __have__ two sides and angles of the same measure while in the scalene triangle all sides and angles are different in side ** lenght?? ?**

Between triangles and square:

While triangle have three sides and angles squares have four sides and angles, __also the__ they both have different theorems to work on them **???**

Between triangles and square:

While triangle have three sides and angles squares have four sides and angles, also thee properties that a triangle has does not apply to the square.
