Answer:

It is an acute triangle

Explanation:

If it is an acute triangle, a^2 + b^2 > c^2

If it is a right triangle, a^2 + b^2 = c^2

If it is an obtuse triangle, a^2 + b^2 < c^2

If it is an equilateral triangle, a = b = c

6^2 +8^2 ? 9^2

36+64 ? 81

100 ? 81

? is >, meaning it is an acute triangle.
