Catherine said to rebecca, "i need to draw an octagon, and i want it to be accurate. rebecca replied, "i have an easy way to draw an octagon. start with a large square. find the midpoint of each side. now draw a line segment from each midpoint to the opposite vertices. in the center of the drawing, an octagon will be formed." "that's a great method but i want to make my octagon a certain size. how big do i need to make the original square in terms of area to get an octagon a certain area? " catherine asked. determine the relationships. also, decide whether the octagon is regular or not.
