1.

**Generate cases:**Drag vertices of the blue and red rectangles to make rectangles of different sizes and at different locations. a. What seems to happen to the coordinates as you drag each vertex? b. Make the following rectangles. Record the coordinates of their vertices in your notebooks. A long, skinny rectangle A square A rectangle with vertex (0,0) A rectangle that is in two quadrants of the coordinate grid 2. Describe**patterns**that you see in the coordinates of the vertices. 3. Make**conjectures**about the relationships between the coordinates of the vertices of any rectangle whose sides are parallel to the x and y-axes. 4.**Justify**one conjecture based on what you know about coordinate geometry. Remember, your conjecture may turn out to be true or false. 5. Write down your**conclusion.**
