How to rotate a line 270 degrees

The video tutorial explains the rules for rotating points 270 degrees counterclockwise, which is equivalent to a 90-degree clockwise rotation. It demonstrates how to apply these rules to transform points and plot them on a graph. The tutorial emphasizes understanding the equivalence between different rotation angles and provides a practical approach to avoid confusion during transformations.

What is the rule for rotating a point 270 degrees counterclockwise?

• Swap coordinates and make the Y coordinate negative

• Swap coordinates and make the X coordinate negative

• Swap coordinates and make both coordinates negative

• Do not swap coordinates, just make the X coordinate negative

When applying the 270-degree counterclockwise rotation rule, what happens to the point (-2, -5)?

• It becomes (-2, 5)

• It becomes (2, -5)

• It becomes (5, -2)

• It becomes (-5, 2)

What is the benefit of using the rotation formula instead of manual plotting?

• It provides more detailed results

• It requires less mathematical knowledge

• It is faster and less confusing

• It is more accurate

How is a 270-degree counterclockwise rotation related to a 90-degree clockwise rotation?

• They result in the same final position

• They are completely different

• They are opposite in direction

• One is twice the other

Which of the following is true about 90-degree counterclockwise and 270-degree clockwise rotations?

• They are equivalent

• They are unrelated

• They result in different final positions

• One is a mirror image of the other
