    This triangle is not a right triangle

    Step-by-step explanation:

    If it were a right triangle, then the pythagorean theorum would work

    a^2 + b^2 = c^2

    12^2 + 7^2 = 15^2

    144 + 49 = 225

    This is not true because 144+49=193, not 225

    So this triangle is not a right triangle

    No

    Step-by-step explanation:

    Formula is a squared + b squared = c squared

    12 times 12 = 144

    7 times 7 = 49

    144 + 49 = 193

    so 15 times 15 should = 193

    but 15 times 15 = 225
