Since a triangle with its angles as 89, 89, 2 exists, it can be an isosceles triangle.
Since a triangle with its angles as 89, 90, 1 exists it can be right triangle or scalene triangle.
So, the answer is All of these \color{#3D99F6}{\boxed{\text{All of these}}}

is that the sum of the two sides of a triangle is always greater than the other side ? but in here in the case of right triangle (89+1=90), its a degenerate one......
