Adjust the sliders for base and height. Drag point C to adjust the slant of the parallelogram. What changes about the shape?

Questions:
1. Adjust the sliders so b = 6 and h = 3. Make sure X = 0. What is the area of the parallelogram?
2. Move the slider for X all the way to the right. What is the resulting shape? What is the area of this shape?
3. How does this prove the formula for the area of a parallelogram? Why must the formulas for the area of a parallelogram and the area of a rectangle be the same? Use complete sentences to explain your reasoning.
