Hint: the 2 45-degree angle legs are equal so both of them equal 1.
The reason that the hypotenuse is equal to sqrt(2) is that all sides on a 45-45-90 triangle are equal except for the hypo, which due to its little bit of extra length needs the sqrt(2) to make it its proper length.
Standards: b. Determine the lengths of sides of 45°-45°-90° triangles.
