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.

Here`s an interesting link for you to revise how math can be defined and classified, and how its
different areas can be described.
