△XYZ is given with X(2, 0), Y(0, −2), and Z(−1, 1).  Which of the following can be used to prove that △XYZ is isosceles?

(2 – (-1))² + (0 – 1)?
and
V(0-(-1))² + (-2 – 1)²
(0 – (–1))² + (–2 – 1)?
and
(2 – 0)² + (0 – (–2))?
V(0 – (-1))² + (-2 – 1)²
and
V(-1– 0)² + (1 – (-2))²
V(2 – 0)² + (0 – (–2))²
and
(2 – (–1))² + (0 – 1)²
