Answer:
No, it is not a right triangle.
Step-by-step explanation:
If the triangle was a right triangle, then the Pythagorean Theorem states that a^2 + b^2 = c^2. Let's test it on this triangle:
13^2 + 14^2 = 365, or c^2. If this is a right triangle, c should equal 15.
However, sqrt(365) = 19.1, which is not 15. So, the triangle is not a right triangle.
