AB = 5 ------- (sqrt((2+3)^2 + 0^2) )
BC = 5 ------- (sqrt(0^2 + (2+3)^2) )
AB = BC
The triangle is isosceles

AB² = 5² + 0² = 25
AC² = 5² + 1² = 26
BC² = 0² + 5² = 25
AB = BC so triangle is isosceles.

gudspeling is right, but you don't even need Pythagoras or square roots.
A and B have the same y coordinate, so AB is clearly of length 5.
B and C have the same x coordinate, so BC is clearly of length 5.
So AB=BC and the triangle is isosceles.
