Answer:
Explanation:
The question as worded on your screen is incomplete and confusing. The reason is that it does not specify whether it should be a counterclockwise or a clockwise rotation.
The image changes depending on which direction the rotation is
I have provided the original triangle ABC(in brown), its image after 90° rotation counterclockwise A'B'C'(in blue) and also another image A"B"C"(in green) which is a clockwise rotation by 90°)
Depending on what your teacher has taught about rotation when no direction specified, choose the right on
I would go first with the counterclockwise rotation image A'B'C'
Hope that helps
