 For Oblique Triangle:
1. When three angles of a triangle are given, we use Sine Law to find the ratio of the sides of the triangle i.e.
                     


2. When two angles and one side of a triangle are given then we use Sine Law to find the remaining sides.


3. When three sides or the ratio of the three sides of a triangle are given then we use Cosine Law to find the three angles i.e.


4. When two sides and included angle are given then first we use Cosine Law and then Sine law to find the remaining parts.

5. When two sides and opposite angle are given then we use Sine law to find the remaining parts.
