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*.*8-76 HW eToo*l (Desmos). Homework Help ✎Describe the shape you have created.

Identify the types of angles at points

*A*,*B*,*C*, and*D*.

There is only one pair of parallel sides.

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