A(n) _____ triangle can never have a right angle.  
For a triangle with sides a, b, c, and opposite angles A, B, C, the law of sines states that _______.  
True or False: An oblique triangle in which two sides and an angle are given always results in at least one triangle.  
 Hint  Answer 
True or False: The law of sines can be used to solve triangles where three sides are known.  
Triangles for which two sides and the angle opposite one of them are known (SSA) are referred to as the
