Answer:
we have the sides of the triangle, which are 14, 5, and 12 inches.
in a right angled triangle, the longest side is the hypotenuse
and pythagoras’s theorem is used/ can be used.
a^b + b^2 = c^2 where c is the hypotenuse
so we know a = 12, b = 5, and c = 14
now check whether the statement is true
we should get c = 14 if it’s a right triangle
12^2 + 5^2 = c^2
144 + 25 = c^2
169 = c^2
√169 = 13 = c
so since we got 13 for c and it’s not 14
we know that this isn’t a right angled triangle
