Move the sliders and drag around point C. Observe how the shape changes.
Questions:
1. Adjust the sliders so that b = 6 and h = 3. What is the area of the orange rectangle? What is the area of the blue triangle?
2. Drag around point C. How does the area of the blue triangle change?
3. Compare triangles ACX and CAD. What do you notice? What about triangles CBX and BCE?
4. What do you notice about the area of the blue triangle and the orange rectangle? If the formula for the area of a rectangle is A = b*h, what is the formula for the area of a triangle? Why?
