The perimeter of a triangle is the sum of the lengths of its three sides. It is an important measurement that is used in a variety of applications, such as construction, engineering, and geometry.

The perimeter of a triangle can also be used to calculate other properties of the triangle, such as its area and the lengths of its angles. It is a fundamental concept in geometry and is used extensively in mathematics and science.

The formula for determining the perimeter of a triangle regardless of its shape is defined as:

\(P\) \(=\) \(AB\) \(+\) \(BC\) \(+\) \(AC\)

\(P\): the perimeter of the triangle

\(AB\): the length between point A and B

\(AC\): the length between point A and C

\(BC\): the length between point B and C

The SI unit of perimeter is: \(meter\text{ }(m)\)
