Answer:
No, it's not a right triangle
Step-by-step explanation:
All right triangles under-go the same criteria: The pythagorean theorem.
This states that a^2+b^2=c^2
a is 12, b is 13, and since 16 is the largest number, it's c.
12^2+13^2=16^2
144+169=256
313=256
This is wrong, so it's not a right triangle.
