Consider first the known side and the adjacent angle. In this diagram, side 'c' is assumed horizontal and of a known length and angle 'B' is known. Because of these constraints, the point 'A' must reside upon the ray extending from point 'B'. The angle at point 'A' is also known.

**Directions**- Move point 'A' until the triangle is complete.
