# The length of each leg of an isosceles right triangle is 4cm, what is the length of the hypotenuse?

#### Answer:

$4 \setminus \sqrt{2} \setminus c m$

#### Explanation:

The length of hypotenuse of an isosceles right triangle with two equal legs each $4 \setminus c m$ is given by Pythagorean theorem as follows

$\setminus \sqrt{{4}^{2} + {4}^{2}}$

$= \setminus \sqrt{32}$

$= 4 \setminus \sqrt{2}$

hence the length of hypotenuse of given isosceles right triangle is

$4 \setminus \sqrt{2} \setminus c m$
