Translations, Rotations, and Reflections

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

• Image

• Preimage

• Rotation

• Reflection

In a translation, how do you move the points of a shape?

• Flip them over a line

• Slide them in the same direction

• Change their size

• Rotate them around a point

What happens to the coordinates when a shape reflects across the x-axis?

• Coordinates switch places

• Only the y-coordinate changes

• Only the x-coordinate changes

• Both coordinates become opposite

When rotating a shape 90 degrees counterclockwise, what happens to the coordinates?

• They switch and the y-coordinate becomes opposite

• They remain the same

• Both coordinates become positive

• They switch and the x-coordinate becomes opposite

What is the center of rotation typically considered to be?

• The midpoint of the shape

• The origin

• The highest point of the shape

• The leftmost point of the shape
