PERIMETRO DE UN TRIANGULO Super facil - Para Principiantes
Understanding the Perimeter of a Triangle
Introduction to Triangles
- Daniel Carrión introduces the topic of triangles, emphasizing that they are figures with three sides and three vertices.
- He explains that vertices are the points where the sides meet, reiterating that a triangle has three vertices.
Definition of Perimeter
- The perimeter is defined as the measure of the contour of a figure, measured in linear units such as centimeters or meters.
- Carrión states that the formula for calculating the perimeter of a triangle is: Perimeter = Side 1 + Side 2 + Side 3.
Example Calculations
First Example: Equilateral Triangle
- An equilateral triangle with all sides measuring 5 cm is presented.
- The calculation shows: Perimeter = 5 cm + 5 cm + 5 cm = 15 cm, concluding that this triangle's perimeter measures 15 cm.
Second Example: Isosceles Triangle
- A second example features an isosceles triangle with side lengths of 6 cm, 10 cm, and 10 cm.
- The calculation reveals: Perimeter = 6 cm + 10 cm + 10 cm = 26 cm, indicating this triangle's perimeter measures 26 cm.
Third Example: Scalene Triangle
- A scalene triangle with side lengths of 8 cm, 6 cm, and 11 cm is introduced for further calculation.
