Which transformation will map an image onto itself?
A translation 3 units right and 3 units up
A rotation 360o clockwise
A reflection over the y-axis followed by a translation 3 units down

What happens when parallel lines are rotated 270o counterclockwise?
The lines intersect
The lines remain parallel
The lines become perpendicular lines
The lines become curved lines
What will be the new position of the given point after a reflection across the y-axis?
The slope of two parallel lines is -1. When the lines are translated 3 units right and 1 unit down, how does this affect the slope?
The slopes remain -1.
The slopes increase by 3.
The slopes decrease by 1.
The slopes become positve.
Which series of transformations were performed in the figure?

Which of the following images shows a rotation of 180o?
The preimage above is rotated 90o counterclockwise. How do the side lengths in the preimage compare to the side lengths in the image?
Some of the side lengths increase in measure and other side lengths decrease in measure.
The measures of the side lengths double.
The measures of the side lengths decrease by one third.
The measures of the side lengths are the same.
