Quiz on Composition of Transformations

What is a glide reflection?

• A combination of rotation and translation

• A combination of translation and reflection

• A combination of scaling and translation

• A combination of reflection and rotation

After a translation, point A is at (3, -3). What is the final image of point A after a glide reflection?

• (1, -3)

• (3, -3)

• (3, 3)

• (0, 0)

What is the result of reflecting a point across the x-axis?

• Both coordinates change sign

• The x-coordinate changes sign

• The y-coordinate changes sign

• Neither coordinate changes sign

How is a translation described in vector notation?

• Using a pair of coordinates in parentheses

• Using a pair of coordinates in curly braces

• Using a pair of coordinates in square brackets

• Using a pair of coordinates in angle brackets

What does a 90-degree counterclockwise rotation do to a point?

• Swaps the x and y coordinates and changes the sign of the new x-coordinate

• Swaps the x and y coordinates and changes the sign of the new y-coordinate

• Only changes the sign of the y-coordinate

• Only changes the sign of the x-coordinate
