Question 859848: A triangle has sides with lengths of 47 inches, 66 inches, and 89 inches. Is it a right triangle?

To test if a triangle is right, you should use the Pythagorean Theorem.
Because the sides 47 and 66 are shorter, they are the legs.
Because 89 is the longest, it is the hypotenuse.
Next, find the squares
Add the numbers together
Because the numbers don't fit in the pythagorean theorem, the triangle is not right.
