8-87.

Graph the following points on a coordinate grid: $A(–3, –3)$, $B(3, 0)$, $C(3, 6)$, $D(–3, 6)$. 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 angles at points $C$ and $D$

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

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

Subtract $3$ from each $x$-coordinate and add $5$ to each $y$-coordinate. For example $A(−3, −3)$ will become$A^\prime(−6, 2)$.

Use the eTool below to graph the points. (Desmos)
