A^2 + b^2 = c^2
<span>C should equal to the longer side, which would be 19. </span>
<span>Plug in other two numbers for A and B. </span>
<span>12^2 + 14^2 = 19^2 </span>
<span>Now see if it's correct. If it is, then it's a right triangle, if it's not then it isn't a right triangle. </span>
<span>144 + 196 = 361 </span>
<span>340 = 361 </span>
<span>It's not a right triangle.</span>
