Question

Which transformations map A’B’C’ in the image above USE COORDINATE ROTATION

Answer 1

Reflection across the x-axis and dilation by a factor of 2.

Step-by-step explanation:

We can see that A'B'C' is a reflection of ABC across the x-axis because they are on opposite sides of x. However A'B'C is greater, its lengths are twice the lengths of ABC, so it is also a dilation by a factor of 2.

Therefore, the transformation that maps ABC to A'B'C' is a reflection across the x-axis and dilation by a factor of 2 about the origin.
