|Given a square of side s and segments drawn from each vertex to the midpoint of the second side, counting counter-clockwise, the segments intersect to form a new square. What is the ratio of the area of the shaded square to the area of the original square? Perhaps this is a "teachable moment" to discuss that in fact the shaded figure is a square. Why are the segments parallel and mutually perpendicular?|
