Can 12,18,30 be a right triangle

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.

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

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.
