Select a type of triangle below
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:
\(P\): 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: \(meter\text{ }(m)\)
Find \(BC\)
Use this calculator to determine the length of BC, when the perimeter and the lengths of AB and AC are given.
