Question

Does A= 6.4 B=12 C=12.2
Form a RIGHT TRIANLGE?

Answer 1

Easy way to find out:

1) Square each number.
2) Add together the squares of the TWO SMALLEST sides.
3) Is that equal to the square of the biggest side?

YES = right triangle.
NO = not a right triangle.

In other words, if \(s_1\) and \(s_2\) are your smallest sides and \(L\) is your largest side then...


\[(s_1)^2+(s_2)^2 = L^2\] is what happens if it's a right triangle.
