Multiple Transformations on a Coordinate Plane

Which transformations would result in a the square being in the same location? (There are multiple correct answers.)

• A 90° counter-clockwise rotation about the origin

• A reflection over the line x = 5.

• A 90° counter-clockwise rotation about the point (5, -5)

• A reflection over the line y = - x.

• A 270° rotation about the point (5, -5)

The line segment is to be reflected over the line shown.

What would be the length of the reflected line segment?

• It would have the same length as the original line segment.

• It would have half the length of the original line segment.

• It would have double the length of the original line segment.

• There is not enough information to know the length of the original line segment.
