Question

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

Answer 1

`4\sqrt2\ cm`

Explanation:

The length of hypotenuse of an isosceles right triangle with two equal legs each `4\ cm` is given by Pythagorean theorem as follows

`\sqrt{4^2+4^2}`

`=\sqrt{32}`

`=4\sqrt2`

hence the length of hypotenuse of given isosceles right triangle is

`4\sqrt2\ cm`
