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.

  1. 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?

  1. 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.
