10416,10)62E(4,2)2 4 6 8 10108 642EX2-4)2 4 6 86640,-6)1. Does the image below, show a rotation of the line segment EF?Yes, ET has been rotated 180 clockwise to form EFI.No, EP has been not been rotated to form EFIYes, EF has been rotated so clockwise to form EFI.Yes, Er has been rotated so counter clockwise to Em

Answer 1

We have to find if E'F' is the image of EF after a rotation.

We can check if it is a rotation around the origin.

If we compare the coordinates of pre-image and image, we can see that they follow this rule:

`(x,y)-->(y,-x)`

This rule correspond to a rotation 90 degrees clockwise.

We can also check with the graph:
