8-76.

Graph the following points on a coordinate graph: $A(-3,-3)$, $B(3,0)$, $C(3,6)$, $D(-3,6)$. Connect the points as you plot them. Then connect point $A$ to point $D$.

1. Describe the shape you have created.

There is only one pair of parallel sides.

2. Identify the types of angles at points $A$, $B$, $C$, and $D$.

Notice that lines $BC$ and $AD$ are perpendicular to line $CD$.

Use the eTool below to plot the points.
