What is the Area and Perimeter of Polygon ABCD graphed above?

## Graph the polygon with vertices (2,1), (2,4), and (7,1)

What is the Area of the triangle graphed above?

## Graph the polygon with vertices A(-2,2), B(-2,5), C(2,5), and D(2,2)

What is the Area AND PERIMETER of the rectangle graphed above?

## Graph the polygon with vertices (0,0), (2,5), (7,5), & (5,0)

What is the Area of the parallelogram graphed above?

## Graph the polygon with vertices (3,5), (4,4), and (3,-1).

What is the Area of the triangle graphed above?

## Graph the polygon with vertices (-5,5), (7,5), (7,-2), and (-5,-2).

What is the Area of the rectangle graphed above?

## Graph the polygon with vertices A(-2,1), B(-2,5), and C(5,1)

Use the Pythagorean Theorem to find the length of side BC. Then determine the perimeter. Show all work.
