The line segment d2 intersects the line segment s2 at a point labeled x2. Two vertical lines labeled q and q2 are drawn perpendicular to the horizontal axis terminating at the points x1 and x2 respectively. Two horizontal lines labeled p2 and p2 are drawn perpendicular to the vertical axis out to the points x1 and x2 respectively.
