The perimeter of a triangle is found by adding the lengths of all three of its sides.
To calculate the perimeter, follow these simple steps:
-
Identify the lengths of all three sides of the triangle. Let's call them side a, side b, and side c.
-
Add the lengths of the three sides together: Perimeter = a + b + c
Example:
Imagine a triangle with sides measuring 5 cm, 7 cm, and 9 cm.
- Side a = 5 cm
- Side b = 7 cm
- Side c = 9 cm
Perimeter = 5 cm + 7 cm + 9 cm = 21 cm
Therefore, the perimeter of this triangle is 21 cm.
In summary, finding the perimeter of a triangle involves a straightforward addition of its three side lengths. This applies to all types of triangles, whether equilateral, isosceles, or scalene.
