If you can describe the term, read on to the next one;

Decide whether a figure is a Saccheri quadrilateral. [7.6]
Once again, see if you can verbalize (to yourself) how
to do each of the listed types of problems. Work all of
Chapter 7 Review Questions (whether they are assigned
or not).
Work through all of the problems before looking at the
answers, and then correct each of the problems. The entire
solution is shown in the answer section at the back of the
text. If you worked the problem correctly, move on to the
next problem, but if you did not work it correctly (or you
did not know what to do), look back in the chapter to study
the procedure, or ask your instructor. Finally, go back
over the homework problems you have been assigned. If you
worked a problem correctly, move on the next problem, but
if you missed it on your homework, then you should look
back in the book or talk to your instructor about how to
work the problem. If you follow these steps, you should
be successful with your review of this chapter.
We give all of the answers to the Chapter Review questions
(not just the odd-numbered questions), so be sure to check
your work with the answers as you prepare for an examination.
