# 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^{2 }+ b^{2}

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.

the hypotenuse is given by ⎷a^{2 }+ b^{2}

We know that,

Perimeter = Sum of all the three sides

= Base + Height + Hypotenuse

So, Perimeter of Right Triangle = a + b + ⎷a^{2 }+ b^{2}

### Hence, the perimeter of a right triangle is a + b + ⎷a^{2 }+ b^{2}
