Perimeter of Right Triangle Calculator

Calculate Your Right Triangle's Perimeter

Quickly determine the perimeter of a right triangle using this free online calculator. Input the lengths of the two shorter sides (legs) 'a' and 'b', and we'll compute the hypotenuse 'c' and the total perimeter 'P' instantly. Simplify your geometry calculations today!

Formula:

The perimeter (P) of a right triangle is the sum of its three sides: two legs (a and b) and the hypotenuse (c). The hypotenuse can be found using the Pythagorean theorem (a2 + b2 = c2).

P = a + b + c
where c = √(a2 + b2)
