**The laws are used for any triangle (doesn’t have to be a right triangle):**

**Less used laws, but they might be helpful once or twice:**

**Solving a triangle:**

When you try to find a triangle using the laws, you might get two different triangles, because

You get two answers from a trig function, and they can be used to make two different triangles, but usually, only the one that actually makes sense is the real one

**Known variables:**

sss, aaa, aas, ssa, sas

s = sides

a = angles**3 angles:** no Solution, can’t be solved

**Oblique triangles:**

Just a triangle that isn’t a right triangle, and can be made into 2 right triangles

**When to use the Law of Sines:**

ASA and AAS can be used with the law of sines

And SSA can also be used but has either no solution, one solution of three solutions

**When to use the Law of Cosine:**

Can be used in SAS and SSS triangles

**How the cosine laws are found:**
