Triangles r s t and v u t are connected at point t. angles r s t and v u t are right angles. the length of side r s is 12 and the length of side s t is 16. the length of side t u is 8 and the length of u v is 6. which statements can be concluded from the diagram and used to prove that the triangles are similar by the sas similarity theorem? startfraction r s over v u endfraction = startfraction s t over u t endfraction and angle s is-congruent-to angle u startfraction r s over v u endfraction = startfraction s t over u t endfraction = startfraction r t over v t endfraction startfraction r s over v u endfraction = startfraction t u over t s endfraction and angle s is-congruent-to angle u startfraction r s over v u endfraction = startfraction t u over t s endfraction = startfraction r t over v t endfraction
