Is a triangle with side lenghts 18, 12, and 22 a right triangle?
mojhsa [17]

Answer: No

Step-by-step explanation:

Pythagorean Theorem goes with a right triangle, the formula is a^2+b^2=c^2.

Let's try this out with your values.

(18*18)+(12*12) = 468

If this is true than c^2 is 468

c^2 or (22*22) is 484 is this is not a right triangle.
