Figure QRTS is reflected about the y-axis to obtain figure Q’R’T’S’: A coordinate plane with two quadrilaterals is shown. Figure QRTS has vertices Q at negative 5 comma 3, R at negative 5 comma 1, S at negative 2 comma 2 and T at negative 2 comma 0. Figure Q prime R prime T prime S prime has vertices Q prime at 5 comma 3, R prime at 5 comma 1, S prime at 2 comma 2 and T prime at 2 comma 0. Which statement best describes the relationship between the two figures? Figure QRTS is bigger than figure Q’R’T’S’. Figure QRTS is congruent to figure Q’R’TS’. The measure of angle R is equal to the measure of angle Q’. The measure of angle S is equal to the measure of angle T’.
