Question ouverte 1
Move the slider to the right, and observe the resulting geometric figure. How do we know that this figure is a parallelogram?

Question ouverte 2
While the slider is in the left-most position, count the number of squares you see. Move the corner points to adjust the size of the rectangle and count the squares again. What does the number of squares represent?

Question ouverte 3
Change the shape to a parallelogram with non-right angles using the slider. Count the number of squares again. What do you notice? Try the same thing with a different shaped parallelogram by moving the points that are not corner points before you slide the slider to the right. How is the area of the parallelogram affected?
