ABC is reflected over the line x = 1, then is rotated -90° around the origin. Then the correct option is A.
What is a transformation of geometry?
A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.
Reflection does not change the size and shape of the geometry. But flip the image.
Rotation does not change the size and shape of the geometry. But change the orientation of the image.
The image of ABC is A'B'C.
First, the triangle ABC is reflected over the line x = 1 to form a new triangle. Then the new triangle is named as A"B"C".
Then the triangle A"B"C" is rotated 90° in the counterclockwise to get the triangle A'B'C'.
ABC is reflected over the line x = 1, then is rotated -90° around the origin.
Then the correct option is A.
