Subject: Teaching area of parallograms

When looking at a parallelogram and determining area, we use the base times the vertical height and not the slanted height. So, I am assuming the slanted height is not equal to the vertical height. I am just unclear about the relationship between the vertical height and the slated "height." Is there a direct relationship? One that can be showed to students and played with? I assume yes and it has to do with area of triangles since you can create a triangle "inside" the parallelogram. Thanks!!!
