Answer:

AB = BC = 4[tex]\sqrt{2}[/tex]

Step-by-step explanation:

This is a 45-45-90 triangle (right isosceles). This means that the side ratio is

1:1:[tex]\sqrt{2}[/tex], where AC is sqrt 2, and AB and BC are 1. Now, we need to plug this into our ratio. If sqrt 2 is 8, then 1 is x.

8/[tex]\sqrt{2}[/tex] = x/1 = x

x = 8/[tex]\sqrt{2}[/tex] = 4[tex]\sqrt{2}[/tex] (rationalized)

AB and BC are both 4 * sqrt 2

The answer is AB = BC = 4√2
