The sum of the squares of the shorter lengths is 5^2 + 12^2 = 25 + 144 = 169.
The square of the longest length is 13^2 = 169.
Therefore, the triangle is a right triangle.

The sum of the squares of the shorter lengths is 6^2 + 7^2 = 36 + 49 = 85.
The square of the longest length is 11^2 = 121.
Therefore, the triangle is an acute triangle.
The square of the longest length is 11^2 = 121.
Therefore, the triangle is an acute triangle.
wrong
I apologize for the error.
The sum of the squares of the shorter lengths is 6^2 + 7^2 = 36 + 49 = 85.
The square of the longest length is 11^2 = 121.
Therefore, the triangle is an obtuse triangle.
The sum of the squares of the shorter lengths is 6^2 + 7^2 = 36 + 49 = 85.
The square of the longest length is 11^2 = 121.
Therefore, the triangle is an obtuse triangle.
