Question

Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm is a right triangle?

Answer 1

A: The triangle is a right triangle because 5 (to the 2nd power) + 12 (to the second power) = 13 (to the second power)

Explanation:

25 + 144 = 169

169 = 169

To determine if it is a right angle, take all three numbers and multiply them by the second power. After you get all the numbers in their second power form, look at the first two numbers. If they equal the same as the third number, that is a right angle.

Answer 2

the pythagoream theorem (not sure if I spelled that right...lol): a^2 + b^2 = c^2......where c is the hypotenuse and it is the longest side

5^2 + 12^2 = 13^2
25 + 144 = 169
169 = 169....(correct)...so it is a right triangle
