    Answer:

    acute isosceles

    Step-by-step explanation:

    Let A(2,5),B(8,3),C(2,1)

    By distance formula,AB=BC=40^0.5

    Hence, it is an isosceles triangle

    Since AC=3, by cosine formula, AC=√(AB^2)+(BC^2)-2(AB)(BC)cosABC

    angle ABC=36.8698765

    Hence,it is an acute isosceles triangle
