ΔEFG has vertices located at E(3,7), F(-1,4), and G(2,1). ΔTUV has vertices located at T(-9,15), U(-1,9), and V(-7,3). Which of the following sequences of transformations, applied to ΔEFG, shows that ΔEFG ~ ΔTUV?
- A translation of 1 unit right and 1 unit up, a rotation of 90° counterclockwise about the origin, and then a dilation of factor 2 centered at the origin.
- A translation of 6 units right and 4 units down, a rotation of 90° about the origin, and then a dilation of factor 2 centered at (3,3).
- A translation of 1 unit right and 1 unit up, a reflection over the y-axis, and then a dilation of factor 2 centered at (1,1).
- A translation of 3 units left and 4 units up, and then a dilation of factor 32 centered at the origin.
