You should KNOW

1. What it means to "solve" a triangle, namely, given some

information about the sides and angles, to find all of them

when this is possible.

2. That, with enough information, right triangles can be

solved by using the Pythagorean theorem, the fact that

the angles sum to 180 degrees, and the definitions of

the trig functions, using your calculator when needed.

3. That non-right triangles can be solved using the Law

of Sines and the Law of Cosines when enough information

is given, and how this is done. That problems involving the

Law of Sines may have two different triangles as solutions.

You do NOT need to memorize these Laws. The formulas

for them (but without pictures) will be provided as needed.

You do need to understand how to use them.

You should be ABLE TO

1. Solve right triangles, and non-right triangles, and apply

these to simple "real" problems.
