How do You Find the Perimeter of a Right Triangle?


Question: How do you find the perimeter of a right triangle?

The perimeter of a right triangle means the sum of its boundary of all three sides

Answer: Perimeter of a right triangle is a + b + ⎷a+ b2  

Let's understand the usage of pythagoras theorem to find the dimensions of the right angled traingle

Explanation:

Let 'a' be the length of the base and 'b' be the length of the height or perpendicular of a right triangle.

By Pythagoras Theorem,

the hypotenuse is given by ⎷a+ b2 

We know that,

Perimeter = Sum of all the three sides

                 = Base + Height + Hypotenuse

So, Perimeter of Right Triangle = a + b + ⎷a+ b2 

Hence, the perimeter of a right triangle is a + b + ⎷a+ b2
