The perimeter of a right triangle is the sum of the lengths of all its sides. In a right triangle, one of the angles is a 90-degree angle, which means that the length of the hypotenuse can be found using the Pythagorean theorem.

The perimeter of a right triangle is useful in many real-life scenarios. For example, when building a roof or a staircase, it is important to know the length of the sides of a right triangle to ensure that the structure is stable and safe. In carpentry, the perimeter of a right triangle can also be used to calculate the length of trim pieces needed for a project.

Additionally, the perimeter of a right triangle can be used to calculate the distance traveled by a person walking in a zigzag pattern between two points. This is known as the Manhattan distance or taxicab distance, and it is commonly used in navigation and computer science algorithms.

Overall, the perimeter of a right triangle has numerous applications in various fields, including construction, carpentry, and navigation.

The formula for determining the perimeter of a right triangle is defined as:
$$P$$ $$=$$ $$AB$$ $$+$$ $$BC$$ $$+$$ $$AC$$
$$P$$: the perimeter of the triangle
$$AB$$: the length between point A and B
$$BC$$: the length between point B and C
$$AC$$: the length between point A and C
The SI unit of perimeter is: $$meter\text{ }(m)$$
