Right angle - c²=a²+b²
Obtuse angle - c²>a²+b²
Acute angle - c²<a²+b²
To see which ones go into a, b, and c, know that the largest number is the hypotenuse (variable c). The other two letters can be either a or b, so it doesn't matter which place they are put it because you will get the same answer.
right angle 14²=6²+13²
196=36+169
196≠205
-----------------------
obtuse angle 14²>6²+13²
196>36+169
196>205 is false
-----------------------
So since it is not a right angle or an obtuse angle, that means that it's a right angle because it's the only option left. Though we now know that's the answer, I will still put down the steps.
acute angle 14²<6²+13²
196<36+169
196<205 is true so it's an acute triangle.
Hope this helps, now you know the answer and how to do it. Stay safe and healthy and HAVE A BLESSED AND WONDERFUL DAY! :-)
