)The other triangle has side lengths 8, 12, and 11.
Compute the sum of the squares of the shorter lengths.
8^2 + 11^2 =
Compute the square of the longest length.
12^2 =
What kind of triangle is it?
Acute triangle
Right triangle
Obtuse triangle
8^2 + 11^2 = 64 + 121 = 185
12^2 = 144
Since 8^2 + 11^2 < 12^2, the triangle is an obtuse triangle.
