\begin{enumerate}
\vspace{-3.5in} \item Use the diagram to the right to answer the \\
following questions. Note this diagram is \\not drawn to scale.

\begin{enumerate}
\item $[1]$ (Wks \#3) Given that \\
$\angle YBC \cong \angle BCA$, what can you \\
conclude about lines $\overline{XY}$ and $\overline{AC}$?\\
(You do not need to justify yourself.)
\vskip .5in
\item $[1]$ (Wks \#3) Treat  $\overline{BC}$ as a \\
transversal of $\overline{XY}$ and $\overline{AC}$.  Identify \\
a pair of alternating interior angles.
\vskip .2in
\item  $[3]$ (Wks \#4) \emph{If} you knew that $\angle BAC \cong 19^\circ$ and $\angle YBC \cong 52^\circ$, find the measure of $\angle ABC$.
\vskip 1.5in
\item $[2]$ Do you trust the measurements quoted above in part (c)? Why or why not?
\end{enumerate}


\vspace{-.5in}\hspace{3.5in} \includegraphics[height=3.5in]{Quiz3b}	
\vspace{-2.5in}\item $[3]$ (Wks \#4) Outline the process of folding a\\
 line perpendicular to $l$ that also passes through\\ 
 the given point.

\vspace{-2in}\item $[2]$ (Lang) The first set of instructions \\
in Chapter 3 produces the following \\
origami model.  What did Lang say this \\
was a model of?

\vspace{1in}


\item $[2]$ (Lang) That is it that makes an origami model inefficient in Lang's view?
\vskip 1.5in

\item $[3]$ (Lang) Justify the following quote found on page 46 of Lang's text:

\hspace{1in} \emph{Generally, the more long points a model has, the smaller}\\

\vspace{-.2in}\hspace{1in} \emph{the final model will be relative to the size f the square.}

\vspace{1.5in}

\item $[3]$ (Lang) Name three bases.  (Both traditional \& standard bases will be accepted.)
