Or today's homework, you will need to recreate work the teacher did last night on their computer. The teacher drew a triangle with vertex A at (1, 4) and vertex B (3, 2). The teacher then transformed it to produce the triangle shown below. You need to find the teacher's original triangle and the transformations they used to create this image. Choose the correct way to find the transformations. Select all that apply. (Hint: It is a rigid transformation.) Which choices show your two correct answers from selecting ways to find transformations?

Step 1 out of 5:
If the teacher's final image has vertex A at (1, 4) and vertex B (3, 2), which transformations could she have used to arrive at this image? Select all that apply.
A rotation
B translation
C dilation
D reflection
