SSS Problem: Determining the largest angle

Practice finding the largest angle of a triangle when lengths of the sides are known.

1) Which angle is the largest? 2) Do you need the picture to know this? 3) Is there a quick way to tell if the triangle is obtuse or acute? 4) Do you need the picture to know that?
