Law of Sines - Why is SSA ambiguous?
 
The ambiguous case occurs when one uses the law of sines to determine missing measures of a triangle when given two sides and an angle opposite one of those angles. In some cases we have zero,one or two solutions. I such cases we assume that there are two possible triangles and we know we are done when we hit a wall. 

The above picture is an example of a one possible solution triangle. As we can see that it gives us two sides and one angle. We first start by finding the missing angles. We use the law of sine to find the "bridge" to the other triangle. Its usually the the same side and angle.


Area formulas - How is the “area of an oblique” triangle derived?  How does it relate to the area formula that you are familiar with?

The area of an oblique triangle is derived by having two side and one angle.
