If the length of one leg in this triangle is .find the length of the hypotenuse.
Sonja [21]

By Pythagorean theorem we find that the length of the hypotenuse is r = \sqrt{2}\cdot l.

<h3>How to find the length of the hypotenuse</h3>

In the image attached we have a <em>right</em> triangle with two legs of <em>same</em> length. The hypotenuse of <em>right</em> triangles can be found by Pythagorean theorem, whose form is:

r = \sqrt{l^{2}+l^{2}}

r = \sqrt{2}\cdot l, where l is the length of the legs.

By Pythagorean theorem we find that the length of the hypotenuse is r = \sqrt{2}\cdot l.
