1. Drag points A, B, C, and D. Describe what happens to the blue rectangle.
2. Predict. What will happen to the coordinates of the vertices of the blue rectangle
• when you drag point A?
• when you drag point B?
• when you drag point D?
Check.
Explain. Describe what changes and what stays the same in the rectangle's coordinates as you drag each point.
3. Record the coordinates of the vertices of the red rectangle in your notebook. What patterns do you see among the coordinates of the vertices
• when you drag point E?
• when you drag point F?
• when you drag point H?
4. Make conjectures about the relationships between the coordinates of the vertices of any rectangle whose sides are parallel to the x and y-axis.
5. Justify your conjectures using what you see in the software and your reasoning.
6. Write down your conclusion.
