Move the points A, B, C and D around and observe how each one effects the image and values.[br][br]1. How does moving Point A effect the values and image?[br]2. How does moving Point B effect the values and image?[br]3. How does moving Point C effect the values and image?[br]4. How does moving Point D effect the values and image?[br]5. What overall observation(s) have you notice about the relationship of the 2 small angles (CBD and ABD) and the overall big angle (CBA)?

Graph the relationship between [math]\angle CBD[/math] (x) and [math]\angle DBA[/math] (y) by moving point D to get multiple points and create a line of best fit. Describe the result and what the graph shows.
