    NO.

    Step-by-step explanation:

    By the Pythagoras theorem if 30^2 = 12^2 + 18^2 it is a right triangle.

    30^2 = 900

    12^2 = 144

    18^2 = 324

    Adding 12^2 + 18^2 = 468 so the answer is no.

    Step-by-step explanation:

    A set of three integers that can be the lengths of the sides of a right triangle is called a Pythagorean triple. The simplest Pythagorean triple is the set "3, 4, 5." These numbers are the lengths of the sides of a "3-4-5" Pythagorean right triangle. The list below contains all of the Pythagorean triples in which no number is greater than 50.

    3, 4, 5

    5, 12, 13 6, 8, 10

    7, 24, 25 8, 15, 17 9, 12, 15 9, 40, 41 10, 24, 26 12, 16, 20 12, 35, 37

    14, 48, 50 15, 20, 25 15, 36, 39 16, 30, 34 18, 24, 30 20, 21, 29 21, 28, 35 24, 32, 40 27, 36, 45 30, 40, 50

    Example Problems

    Find the length of the missing side.

    13 25 x7

    12 x

    From the list above, the missing From the list above, the missing side is "5" side is "24"

    Show why the set "6,8,10" is a Pythagorean triple.

    c2 = a2 + b2 102 = 82 + 62 100 = 64 + 36 100 = 100

    Since the Pythagorean equation is satisfied, the set "6,8,10" is a Pythagorean triple.
