The circumference of a triangle is simply the sum of the lengths of all three of its sides.
To find the circumference of a triangle, follow these steps:
-
Identify the lengths of all three sides of the triangle. Let's call these sides a, b, and c.
-
Add the lengths of the three sides together. The formula is:
Circumference = a + b + c
Example:
Let's say you have a triangle with sides of length 5 cm, 7 cm, and 9 cm.
- a = 5 cm
- b = 7 cm
- c = 9 cm
Circumference = 5 cm + 7 cm + 9 cm = 21 cm
Therefore, the circumference of this triangle is 21 cm.
In summary: Finding the circumference of a triangle is straightforward – just add the lengths of its three sides. This total length represents the distance around the triangle.
