Converse of the Pythagorean theorem: is it a right triangle?

Full solution

Q. A triangle has sides with lengths of

12\,\text{feet}

,

16\,\text{feet}

, and

18\,\text{feet}

. Is it a right triangle?

\newline

Choices:

\newline

(A)yes

\newline

(B)no

Identify Longest Side: Identify the longest side to test for the right triangle using the Pythagorean theorem. $\newline$ Reasoning: The longest side should be the hypotenuse in a right triangle. $\newline$ Calculation: The sides are $12\,\text{ft}$ , $16\,\text{ft}$ , and $18\,\text{ft}$ . The longest side is $18\,\text{ft}$ .
Apply Pythagorean Theorem: Apply the Pythagorean theorem to check if it's a right triangle. $\newline$ Reasoning: For a right triangle, the sum of the squares of the two shorter sides should equal the square of the longest side. $\newline$ Calculation: $12^2 + 16^2 = 144 + 256 = 400$ , $18^2 = 324$ .
Compare Results: Compare the results to determine if it's a right triangle. $\newline$ Reasoning: If $12^2 + 16^2$ equals $18^2$ , then it's a right triangle. $\newline$ Calculation: $400$ does not equal $324$ .
