Polygons on the Coordinate Plane

The drawing shows points A, B, and C. At what location would you add point D to create a square?

Jim plotted points A and B on the coordinate grid. He wants to add a point C to create a right triangle. Which of the following coordinates would not create a right triangle?

The vertices of the giraffe exhibit at a Zoo are E(0,90), F(60, 90), G (100,30), and H (0,20). The coordinates are measured in feet. What is the area of the exhibit? PAY CLOSE ATTENTION TO THE SCALES ON THE AXES. (They're in increments of 10)

You design a tree house using a coordinate plane. You plot the vertices of the floor at J (2, 1), K (2, 8), L(9, 8), and M (9, 1). The coordinates are measured in feet. What is the area of the tree house?

What is the length of line segment AC?
