To test if a triangle is right, you should use the Pythagorean Theorem.
a%5E2%2Bb%5E2=c%5E2
Because the sides 47 and 66 are shorter, they are the legs.
47%5E2%2B66%5E2=c%5E2
Because 89 is the longest, it is the hypotenuse.
47%5E2%2B66%5E2=89%5E2
Next, find the squares
2209%2B4356=7921
Add the numbers together
6565=7921

Because the numbers don't fit in the pythagorean theorem, the triangle is not right.
