**To solve an oblique triangle, we need to know at least one side and any two other parts of the triangle. We get the following 4 cases: Two angles and any side (AAS or ASA) Two sides and an angle opposite one of them (SSA) Three sides (SSS) Two sides and their included angle (SAS) We use the Law of Sines for the first two cases. Law of Sines. If ABC is a triangle with sides a, b, and c, then ...

If ABC is a triangle with sides, a, b, and c, then *** To solve an oblique triangle you need to know the measure of at least one side and any two other parts of the triangle. Law of Cosines: *** Use the Law of Cosines when you ONLY have sides *** After you use Law of Cosines ONCE then you can use Law of Sines. DeMoirvre’s Theorem: If is a complex number and n is a positive integer, then ...

An oblique triangle is one that has no right angle. The three angles can be acute (all angles less than 900) or one angle can be obtuse (greater than 900) and the remaining two angles acute. Regardless of what scenario exists, the measure of unknown angles and the lengths of unknown sides can be determined by using either the Law of Sines or the Law of Cosines. Let us look first at the Law of ...
