If a triangle has sides 12, 13 and 16, is it a right triangle? Show your work

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.
