|dw:1379258287660:dw| use the figure as a guide. then apply your Law of Sines to figure out the interior angles. If ALL interior angles are less than 90 degrees, then it is acute. If one of the interior angle is greater than 90 degrees then it is obtuse. if one of the interior angle is 90 degrees, then it is right triangle.
