Polygon pqrst shown below is dilated with a scale factor of 3, keeping the origin as the center of dilation: two polygons are drawn on a coordinate grid. polygon pqrst has vertices at p 0 and negative 3, q 3 and negative 2, r 3 and 1, s 0 and 2, t negative 2 and 0. polygon p prime q prime r prime s prime t prime has vertices at p prime 0 and negative 9, q prime 9 and negative 6, r prime 9 and 3, s prime 0 and 6, and t prime negative 6 and 0. which statement about polygon pqrst and its image after dilation, polygon p'q'r's't', is correct? the lengths of side rq and side r'q' are in the ratio 1: 3. the length of diagonal rt is equal to the length of diagonal r't'. the measures of angle s and angle s' are in the ratio 1: 3. the length of side pq is equal to the length of side p'q'.
