In right triangle:
a² + b² = c²
49 , 64 , 80
80² = 6400
49² + 64² = 2401 + 4096 = 6497 ≠ 80²
45 , 60 ,75
75² = 5625
45² + 60² = 2025 + 3600 = 5625 = 75²
48 , 55 , 72
72² = 5184
48² + 55² = 2304 + 3025 = 5329 ≠ 72²
34 ,56 , 65
65² = 4225
34² + 56² = 1156 + 3136 = 4292 ≠ 65²
So 45 , 60 ,75 are sides of a right triangle.
