What is the center of rotation used in most problems discussed in the video?

• The point (1,1)

• The point (2,2)

• The point (-1,-1)

• The origin (0,0)

In the context of rotations, what is the default direction unless otherwise specified?

• Downward

• Upward

• Counterclockwise

• Clockwise

Which of the following angles is equivalent to a 270-degree clockwise rotation?

• 360-degree counterclockwise

• 270-degree counterclockwise

• 180-degree counterclockwise

• 90-degree counterclockwise

When rotating a point 270 degrees counterclockwise, what happens to the coordinates?

• They switch places and the new y-coordinate becomes negative

• They switch places and the new x-coordinate becomes negative

• They switch places and both become negative

• They remain the same

What is the new position of point J (-2, 4) after a 180-degree rotation?

• (2, 4)

• (-2, -4)

• (-4, 2)

• (2, -4)

What should you avoid when choosing points to map rotations?

• Points with both coordinates as zero

• Points with positive coordinates

• Points with coordinates like (1, -1) or (2, 2)

• Points with negative coordinates

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

• Both coordinates change sign

• The y-coordinate changes sign

• The x-coordinate changes sign

• Neither coordinate changes sign

In a composition of transformations, what is the first step if not specified otherwise?

• Perform the rotation first

• Perform the translation first

• Perform the reflection first

• Perform any transformation first

What is the final position of point N (-1, -2) after reflecting over the x-axis and then rotating 180 degrees?

• (1, -2)

• (-1, -2)

• (-1, 2)

• (1, 2)

What is a key characteristic of a rotation in terms of the figure's properties?

• It only changes the angles of the figure

• It changes the size of the figure

• It preserves the size and shape of the figure

• It changes the shape of the figure
