7-11.

Graph the following points on a coordinate grid: *A**B**C**D**A *to point *D*.

Describe the shape you have created.

There is only one pair of parallel sides.

Identify the angles at points

*C*and*D*.Notice that lines

*BC*and*AD*are perpendicular to line*CD*.

Record the coordinates of the new points if you were to translate the original points three units left and five units up.

Subtract

from each -coordinate and addto each -coordinate. For example*A*will become *A*'.

Use the eTool below to graph the points.
