## Answers ( )

Answer:

acute isosceles

Step-by-step explanation:

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
