The theorem states that if we have a right triangle then a 2 + b 2 = c 2 where c is the length of the hypotenuse and a and b are the leg lengths. By using the inverse of the theorem we can determine if the triangle is obtuse or acute. Figure 4 shows which formula to use when solving for acute or obtuse triangles.
