Step-by-step explanation:

45 - 45 - 90 Triangles

When one leg = x, the hypotenuse = x $\sqrt{2}$

So, if the hypotenuse is 1, then divide by $\sqrt{2}$ to get the leg.

$\frac{1}{\sqrt{2} }$ rationalize denominator.

$\frac{1}{\sqrt{2}}$ × $\frac{\sqrt{2}}{\sqrt{2} }$ = $\frac{\sqrt{2}}{\sqrt{2} \sqrt{2} }$ = $\frac{\sqrt{2} }{\sqrt{4}}$ = $\frac{\sqrt{2}}{2}$
