Question

How do you use the Pythagorean Theorem to determine if the three sides are a right triangle: 48.5 ft, 39 ft, 32.5 ft?

Answer 1

Just check `a^2+b^2 = c^2` where `c` is the largest value.

`32.5^2+39^2 = 1056.25 + 1521 = 2577.25`

`48.5^2 = 2352.25`

`2577.25 != 2352.25` so this triangle is not right angled.
