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

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.
