Complete the statements to verify that the triangles are similar.

startfraction q r over t u endfraction = a.1/4 b.1/2 c.2 d.4

startfraction p r over s u endfraction = a.1/2 b.2 c.4 d.6

startfraction p q over s t endfraction = startfraction startroot 52 endroot over startroot 13 endroot endfraction = a.1/2 b.2 c.4 d.6

therefore, △pqr ~ △stu the theorem. a. sas congruency b. sas similarity c. sss congruency d. sss similarity
