Part E Open the line segment rotation application. Line segment AB is a 90° rotation counterclockwise of line segment CD. Click the 90° counterclockwise button. Are line segments AB and CD the same? What does this mean about how a line segment changes when you rotate it?

Part F
Open the line segment reflection application. Line segment AB is a reflection of line segment CD across the x-axis. Click the reflect over x-axis button. Are line segments AB and CD the same? What does this mean about how a line segment changes when you reflect it?

Part G
Using the same application you used in Part F, reflect the line segment across the x-axis. Then, rotate it 90° clockwise. Finally, translate it down 2 units. What is the relationship between the original line segment and the transformed line segment? If you transform a line segment with a sequence of reflections, rotations, or translations, is it still a line segment?
