Transformations in Geometry Quiz

What happens to the coordinates (X, Y) when a point is rotated 90 degrees counterclockwise about the origin?

• (-Y, X)

• (-X, -Y)

• (Y, -X)

• (X, Y)

In a translation, if a point moves four units to the right and one unit down, what happens to its coordinates?

• X increases by 4, Y decreases by 1

• X decreases by 4, Y increases by 1

• X increases by 4, Y increases by 1

• X decreases by 4, Y decreases by 1

When translating a figure one unit right and one unit up, what is the change in the coordinates?

• X decreases by 1, Y increases by 1

• X increases by 1, Y decreases by 1

• X increases by 1, Y increases by 1

• X decreases by 1, Y decreases by 1

What remains unchanged when reflecting a point across the x-axis?

• Both coordinates

• The y-coordinate

• The x-coordinate

• Neither coordinate

How does the y-coordinate change when a point is reflected across the x-axis?

• It doubles

• It changes sign

• It remains the same

• It becomes zero

What type of transformation is it when a figure is moved without changing its orientation?

• x = 0

• y = 3

• y = 0

What type of transformation involves rotating a figure 180 degrees about the origin?
