Question

which transformations could have occurred to map △abc to △a\b\c? a rotation and a reflection a translation and a dilation a reflection and a dilation a dilation and a rotation

Explanation:

1. First, observe the size: $\triangle A''B''C$ is smaller than $\triangle ABC$, so a dilation (size change) must have occurred.
2. Next, observe the orientation: the angle at $A$ and the angle at $A''$ are on opposite sides of the line $AC$, which indicates a reflection (flip over a line) has occurred. Rotation, translation alone would not flip the orientation, and rotation combined with dilation would not create this mirrored angle alignment.

Answer:

a reflection and a dilation
