Now before going for the topic " solving general
triangles", a student must know some important results which
are known as "properties of triangles" you are already
known to Law of sines, Law of cosines and Law of tangent etc. in
addition to this you must know the following formulas as well.

where s = 1 /2 (a + b + c) i.e. half the perimeter
of triangle ABC.
Solving General Triangles
It is a procedure which can be categorized into
several distinct groups, depending upon the nature and contains
of a problem.
SSS : To Solve the triangle when all the three
sides are given.
Example
Suppose a, b and c are given, use Law of cosines
for each angle,
1. Solve D ABC, given a = 30.3, b =
40.4 and C = 62.6
