Determine whether XYZ is scalene, isosceles, or equilateral

Question

Answer isosceles and work
xy = (4 - 2) ^ 2 + (2 - 2) ^ 2

= 36 + 4 = 40 =2/10|

XZ * (4 + 2) ^ 2 + (2 + 0)

YZ = 2 ^ 2 + 4 ^ 2 = 20 = 2/5

= 4 = 16 = 20 = 2/5

Is this correct

Answer 1

It appears that two sides are the same length, so yes, that would be isosceles.
