Question

Explain in 3-5 steps how to find the perimeter of the following non-right triangle.

Answer 1

To find the perimeter of a non-right triangle, follow these steps:

1. **Identify the Lengths of the Sides**: Obtain measurements for all three sides of the triangle. Let's denote these sides as \( a \), \( b \), and \( c \).

2. **Add the Side Lengths**: Use the formula for the perimeter, which is the sum of the lengths of all sides.

\[
\text{Perimeter} = a + b + c
\]

3. **Calculate the Result**: Perform the addition to find the perimeter.

For example, if the lengths of the sides are \( a = 5 \), \( b = 7 \), and \( c = 9 \):

\[
\text{Perimeter} = 5 + 7 + 9 = 21
\]

4. **Conclusion**: The resulting sum is the perimeter of the triangle. In this example, the perimeter is 21 units.

5. **Units**: Ensure that the perimeter is expressed in the appropriate units based on the measurements of the sides (e.g., centimeters, meters).
