Determine whether the following lengths represent a right triangle. 5. 8. 9

This is not a right triangle

Step-by-step explanation:

To determine if these lengths are a right triangle we can use the Pythagorean Theorem

a^2 + b^2 = c^2

so

5^2 + 8^2 = 9^2

25+64=81

25+64 is not 81, it is 89

Therefore, this triangle is not a right triangle
