Transformations and Their Effects

What is the term used for the original shape before a transformation?

• Image

• Preimage

• Reflection

• Rotation

In a translation, how do all points of a shape move?

• Only vertically

• Only horizontally

• Same distance in the same direction

• Different distances in different directions

If a shape is translated 3 units left and 5 units up, what happens to the x and y coordinates?

• Add 3 to both x and y

• Subtract 3 from x, add 5 to y

• Subtract 3 from both x and y

• Add 3 to x, subtract 5 from y

What happens to the coordinates of a point when it is reflected across the x-axis?

• Coordinates remain the same

• Both coordinates change sign

• The y-coordinate changes sign

• The x-coordinate changes sign

During a 90-degree rotation around the origin, what happens to the coordinates?

• Coordinates remain the same

• x and y switch, y changes sign

• x and y switch, x changes sign

• Both x and y change sign
