Question

A triangle has sides with lengths of 12 feet, 16 feet, and 18 feet. Is it a right triangle?

Answer 1

No, it is not a right triangle.

Explanation:

Right triangle fulfill the pythagorean theorem:

`a^2+ b^2 = c^2`

Where, c is the hypothenuse or the longest side, and b and a are the remaining two sides.

`12^(2) = 144\\16^2 = 256\\256 + 144 = 400\\\sqrt {400} = 20 \\eq 18`

Answer 2

Step-by-step explanation: If the sides are a,b,c (in ascending order) and c squared = the sum of the squares of a and b, then it's a right triangle.
