    Nope

    Step-by-step explanation:

    Hypotenuse = 14

    Use Pythagoras' Thereom:

    /sqrt{12^2+5^2}=13

    The equation did not equal the hypotenuse, therefore it is not a right-angled triangle.

    no

    Step-by-step explanation:

    You use the Pythagorean Therom and square your legs (5 and 12) and your hypotenuse (14) it would add up to 25+144=196.

    This is not true since 144+25 is 169, not 196
