Answer:

So we know that this is a right isosceles triangle because 2 sides are equal and there's a 90 degree angle,

In an isosceles right triangle, the sides are in the ratio 1:1:[tex]\sqrt{2}[/tex]

a^2 + b^2 = c^2

We use the Pythagorean Theorem, where a and b are the legs and c is the hypotenuse.

2(2^2)=c^2

c=2[tex]\sqrt{2}[/tex]
