On graph paper, plot $ABCD$ if $A(-1,2)$, $B(0,5)$, $C(2,5)$, and $D(6,2)$.  

1. What type of shape is $ABCD$? Justify your answer.

2. If $ABCD$ is rotated $90º$ counterclockwise ($\circlearrowleft$) about the origin, name the coordinates of the image $A'B'C'D'$.

3. On your graph, reflect $ABCD$ across the $y$-axis to find $A''B''C''D''$. Name the coordinates of $A''$ and $C''$.

4. Find the area of $ABCD$. Show all work.

   Hint (d):

   $\text{Area of a trapezoid}=\frac{1}{2}(b_1+b_2)h$
