No. For a triangle with sides 21, 71, 77 (largest side 77) check the converse of the Pythagorean theorem:
21^2 + 71^2 = 441 + 5041 = 5482, while 77^2 = 5929.
Since 5482 ≠ 5929, the triangle is not a right triangle.
21^2 + 71^2 = 441 + 5041 = 5482, while 77^2 = 5929.
Since 5482 ≠ 5929, the triangle is not a right triangle.
