The figure shows two triangles on a coordinate grid: a coordinate plane with two triangles is shown. triangle rst has vertices r at 3 comma 4, s at 1 comma 1, and t at 5 comma 1. triangle r prime s prime t prime has vertices r prime at 2 comma negative 3, s prime at negative 1 comma negative 1 and t prime at negative 1 comma negative 5. what set of transformations is performed on triangle rst to form triangle r′s′t′?
