Understanding 90-Degree Rotations

What is the main focus of this tutorial?

• Translating objects

• Reflecting objects

• Scaling objects

• Rotating objects 90 degrees

In which quadrant does triangle ABC start before the clockwise rotation?

• Quadrant 4

• Quadrant 3

• Quadrant 1

• Quadrant 2

What happens to the x and y values during a 90-degree clockwise rotation?

• They remain the same

• They are switched

• They are multiplied

• They are added together

After a 90-degree clockwise rotation, what will be the sign of the coordinates in quadrant 1?

• X negative, Y positive

• X positive, Y negative

• Both negative

• Both positive

Which direction is used for the second rotation of triangle ABC?

• Clockwise

• Counterclockwise

• Upward

• Downward

In which quadrant does triangle ABC end up after a 90-degree counterclockwise rotation?

• Quadrant 4

• Quadrant 3

• Quadrant 2

• Quadrant 1

What is the sign of the coordinates in quadrant 3 after a counterclockwise rotation?

• X negative, Y positive

• Both negative

• Both positive

• X positive, Y negative

What forms a right angle during the rotation of the axes?

• The original and new locations of point C

• The original and new locations of point A

• All of the above

• The original and new locations of point B

What happens to the axes during a 90-degree rotation?

• They remain unchanged

• They switch places

• They disappear

• They become parallel

What is the first step in performing a 90-degree rotation?

• Multiply the coordinates

• Switch the absolute values of x and y

• Reflect the coordinates

• Add the coordinates
