You can fool around with this... OR YOU CAN DO AN EXPERIMENT!!! As you can see when you move the yellow dots, (draggable) the red ones find the midpoint of each line and thread a line through each midpoint. It will create 5 triangles. 1 is the big one with black lining. And 2, 3, 4,and 5 being the triangles inside. Each triangle should be identical just different sizes and flipped.
