The idea is to connect geometry to algebra by way of variables. [br][br](1) Start off moving point B. The point on the graph is located at the point (c, t1) where "c" is the length of the segment connecting A and B (across from angle C). t1 is the area of the triangle. As you move B the length of c changes and the area (t1) changes. What do we notice about the graph?[br][br](2) To erase the graph just click and drag the graph up and down slightly. [br][br](3) Experiment with ways of getting different graphs (e.g., try moving A to a different place, try starting with C in a different place, then move B).[br][br](4) Experiment with ways of getting the same graph but with vertices A or C starting in different places.[br][br]** The curved back arrow at the top of the screen will allow you to "undo" your actions.[br][br]** Sometime it is easier to simply reload this page.
