Answer
the triangle is a right triangle with the hypotenuse $c=10$.
Work Step by Step
For a right triangle with legs $a$, $b$ and the hypotenuse $c$, the Pythagorean theorem states that:
$$c^2=a^2+b^2.$$
We plug in the side lengths to check if the triangle is right:
$$
\sqrt{6^2+8^2}=\sqrt{100}=10
.$$
This statement is true, so the triangle is right with $c=10$.
