Classification Assignment I. Visit the following link and draw a graphic organizer showing the classification of triangles. Work only with the types of triangles. http://en.wikipedia.org/wiki/Triangle#Types_of_triangles Types of triangles Triangles can be classified according to: By internal angles By relative lengths of sides Equilateral triangle Isosceles triagle Scalene triangle All sides have the same lengths, Regular polygon. all angles measuring 60° Two sides are equal in length. An isosceles triangle also has two angles of the same measure all sides are unequal. The three angles are also all different in measure Triangles that do not have an angle that measures 90° acute-angled triangle. A triangle that has all interior angles measuring less than 90° obtuse-angled triangle. A triangle that has one angle that measures more than 90° Oblique triangles Has one of its interior angles measuring 90° A "triangle" with an interior angle of 180°° Right-angled triangle Degenerate. II. Write the classification of the mathematical term you defined and described in the last wiki activity Cube: Geometric body, Three dimensions Obtuse angle: Type the triangles, “By the internal angles” Rectangle Geometric: body, two dimensions. Square: Geometric body, two dimensions. For further information about writing classifications please visit the following links: http://essayinfo.com/essays/classification_essay.php http://www.io.com/~hcexres/textbook/class.html Here`s an interesting link for you to revise how math can be defined and classified, and how its different areas can be described.
