The video tutorial covers Grade 8 math rotations, focusing on rotating points around the origin. It explains the steps for performing rotations, including reading coordinates, identifying the center of rotation, and understanding rotation direction. The tutorial provides examples of 90° and 180° rotations, both clockwise and counterclockwise, and discusses how coordinates change during these transformations. The video concludes with a summary of rotation rules.

What is the main difference between the Grade 8 and Grade 7 rotation lessons?

• Grade 8 does not involve any rotations.

• Grade 8 includes rotations of points far from the origin.

• Grade 8 focuses on rotating points close to the origin.

• Grade 8 only covers clockwise rotations.

What is the first step in performing a rotation?

• Choose a random pivot point.

• Determine the direction of rotation.

• Read the coordinates of the object.

• Draw a mental rectangle.

In Grade 8, what is always used as the center of rotation?

• The midpoint of the object.

• The origin.

• A random point on the grid.

• The top-right corner of the grid.

What happens to an object in Quadrant 1 when rotated 90° counterclockwise?

• It moves to Quadrant 2.

• It moves to Quadrant 3.

• It stays in Quadrant 1.

• It moves to Quadrant 4.

If an object in Quadrant 1 is rotated 90° clockwise, where does it end up?

• Quadrant 1

• Quadrant 4

• Quadrant 3

• Quadrant 2

How do the coordinates change when a point is rotated 90° clockwise?

• The coordinates are swapped without sign change.

• Both coordinates remain the same.

• The y-coordinate becomes negative and switches with x.

• The x-coordinate becomes negative and switches with y.

What is the effect of a 90° counterclockwise rotation on the coordinates?

• The x-coordinate becomes negative and switches with y.

• The y-coordinate becomes negative and switches with x.

• The coordinates are swapped without sign change.

• Both coordinates remain the same.

What is the result of rotating a point 180°?

• It moves to the opposite quadrant.

• It stays in the same quadrant.

• It moves to the adjacent quadrant.

• It disappears from the grid.

What is the rule for a 180° rotation regarding coordinate signs?

• Both coordinates change signs.

• Only the x-coordinate changes sign.

• Only the y-coordinate changes sign.

• Neither coordinate changes sign.

Which of the following is true about 180° rotations?

• They result in a straight line through the origin.

• They require a specific direction.

• They only affect the y-coordinate.

• They only affect the x-coordinate.
