Rotation Rules: Clockwise and Counter Clockwise Angles

This video tutorial explains the rules for rotating points on a coordinate plane both clockwise and counterclockwise. It covers the specific transformations for 90, 180, 270, and 360 degrees rotations. Examples are provided to illustrate the application of these rules, including rotating a triangle 90 degrees clockwise and 180 degrees counterclockwise. The video concludes with a summary and a call to action for viewers to subscribe and like the content.

What happens to the coordinates when rotating 90 degrees clockwise?

• Coordinates remain the same

• Switch x and y, negate x

• Switch x and y, negate y

• Negate both x and y

For a 180 degrees clockwise rotation, what should be done to the coordinates?

• Switch x and y, negate x

• Negate both x and y

• Coordinates remain the same

• Switch x and y, negate y

In a 270 degrees clockwise rotation, what is the rule for the coordinates?

• Negate both x and y

• Coordinates remain the same

• Switch x and y, negate y

• Switch x and y, negate x

What are the new coordinates of point A (0, 1) after a 90 degrees clockwise rotation?

• (1, 0)

• (0, -1)

• (1, -1)

• (1, -0)

What are the new coordinates of point B (2, 1) after a 90 degrees clockwise rotation?

• (2, 1)

• (2, -1)

• (1, -2)

• (1, 2)

What happens to the coordinates when rotating 90 degrees counterclockwise?

• Switch x and y, negate y

• Switch x and y, negate x

• Negate both x and y

• Coordinates remain the same

For a 180 degrees counterclockwise rotation, what should be done to the coordinates?

• Switch x and y, negate y

• Switch x and y, negate x

• Coordinates remain the same

• Negate both x and y

In a 270 degrees counterclockwise rotation, what is the rule for the coordinates?

• Switch x and y, negate x

• Switch x and y, negate y

• Negate both x and y

• Coordinates remain the same

What are the new coordinates of point A (1, 3) after a 180 degrees counterclockwise rotation?

• (-1, 3)

• (1, -3)

• (-3, -1)

• (-1, -3)

What are the new coordinates of point B (2, 1) after a 180 degrees counterclockwise rotation?

• (-2, -1)

• (-2, 1)

• (-1, -2)

• (2, -1)
