9.0 Secant-Secant Product Theorem
It is highly beneficial to prove the theorems in sections 9-5 through 9-7. This can help you understand and remember them much more easily.
Here, an example is provided for theorem 9-12 (the secant-secant product theorem), which students often misunderstand. Again, you may find it useful to do something similar on your own for the other theorems in this chapter.
