We know that In <span>a right triangle c</span>²=a²+b² where a and b are the legs of triangle c is the hypotenuse of the triangle so
case 1)7,24,25 25²=7²+24² 25²-----> 625 7²+24²----> 625 625 is equal to 625----------> <span>form a right triangle </span> case 2) 7,23,24 24²=7²+23² 24²------> 576 7²+23²-----> 578 576 is not 578-------------> not form a right triangle
case 3) 7,25,26 26²=7²+25² 26²-----> 676 7²+25²-----> 674 676 is not 674-----> not form a right triangle
