If δopq is dilated from point q by a scale factor of 3, which of the following equations is true about segment r prime s prime?

triangle opq is shown with point r lying on side op and point s lying on side oq line rs is perpendicular to side oq.

segment r prime s prime = one half segment rs
segment r prime s prime = two segment rs
segment r prime s prime = segment rs
segment r prime s prime = three segment rs
