The answer is the last choice. It says the triangle is dilated by a scale factor of . To check this we can just look at the side lengths if the triangles. has a length of 8 by looking at the graph, and has a length of 2 from the graph too. So when we put those lengths into a fraction, it simplifies to . The only answer that says this is the last answer choice.
Triangle ABC is similar to triangle A prime B prime C prime. because triangle A prime B prime C prime. is obtained by dilating Triangle ABC.by a scale factor of 1 over 4. and then rotating it about the origin by 180 degrees
