 * I. Visit the following link and draw a graphic organizer showing the classification of triangles. Work only with the types of triangles. **


 * = **By relative length of sides** || Equilateral triangle

All its sides have the same length || Isosceles triangle

Two sides are equal in length || Scalene triangle

All its sides are of different length || Has an internal angle measuring 90º || Obtuse triangle Has an internal angle measuring more than 90º || Acute triangle All its angles measure less then 90º ||
 * = **By internal angles** || Right triangle


 * II. Write the classification of the mathematical term you defined and described in the last wiki activity **

We can classify the natural numbers into those that are odd and even. Even natural numbers: those that can be expressed in the form 2·k, where k is a natural number, eg. 2·3 = 6. Odd natural numbers: those that can be expressed in the form 2·k+1, where k is a natural number, eg. 2·3+1=7

We can also classify them into prime and composite numbers Prime numbers: those whose only divisor are themselves and 1, eg. 5 Composite numbers: those that have a divisor which is other than one and itself, eg. 6, whose divisors are 3, 2 and 1.
