Answer: 
 See the picture attached.
 The shape created is a Triangle.
Explanation:
 The missing part is: "Connect them in order: A to B, B to C, C to D, and then D back to A. What shape is created?"
 
 For this exercise it is important to remember that, given a point 
 , "x" is the the x-coordinate of the point and "y" is the y-coordinate of the point.
, "x" is the the x-coordinate of the point and "y" is the y-coordinate of the point.
 In this case, Ms. Juhal has the following points:
 1) Point 

 Where you can identify that:
 

 2) Point 

 Where:
 

 3) Point 

 Where you can observe that:
 

 4) Point 

 Where:
 

 Therefore, knowing the coordinates of each point, you can plot them and connect them in order (Observe the picture attached).
 Finally, you can identify that the shape created is a Triangle.
