Set up a four quadrant graph and graph the points below to make the four-sided shape .

Plot the points ,

*,*

*, and*

*with their respective coordinates to form the four-sided shape.*

What shape is

?Look closely at the shape created by the points. Do you notice any special characteristics about the shape?

Did you notice that it had a pair of parallel sides?

Find the area of the shape.

Consider the trapezoid as separate parts and visualize the parts reconstructed as a rectangle.

Try summing the area of the different pieces.Use the formula below from the Math Notes box in Lesson 1.1.2 for extra help to calculate the area of the trapezoid.
