Geometry Rotations Quiz

What is the main difference between clockwise and counterclockwise rotations?

• Counterclockwise rotations follow the direction of a clock's hands.

• Clockwise rotations follow the direction of a clock's hands.

• Counterclockwise rotations are always negative.

• Clockwise rotations are always positive.

When rotating a shape 90 degrees counterclockwise, what happens to the coordinates?

• The x-coordinate remains the same.

• The x and y coordinates are swapped.

• The y-coordinate is negated.

• The x-coordinate is negated.

Which of the following is a rule for 180-degree rotation?

• Swap x and y coordinates.

• Negate both x and y coordinates.

• Negate the y-coordinate only.

• Negate the x-coordinate only.

In the example of rotating triangle ABC -90 degrees, what is the first step?

• Draw a new axis from the origin.

• Draw a new axis from the point of rotation.

• Calculate the new coordinates directly.

• Use a protractor to measure angles.

What is the effect of a -90 degree rotation on a shape?

• It flips the shape horizontally.

• It rotates the shape counterclockwise.

• It rotates the shape clockwise.

• It flips the shape vertically.

What is the key step in verifying the accuracy of a rotated shape?

• Estimate the new position visually.

• Recalculate the original coordinates.

• Check the distance between points.

• Use a calculator for precision.

What is the primary purpose of drawing a new axis when rotating around a point other than the origin?

• To simplify calculations.

• To visualize the rotation.

• To measure angles accurately.

• To align with the original axis.

What is the result of rotating a point 90 degrees counterclockwise?

• The y-coordinate is negated.

• The x-coordinate is negated.

• The x-coordinate becomes the y-coordinate.

• The y-coordinate becomes the x-coordinate.

How do you determine the new position of a point rotated 90 degrees without a coordinate plane?

• Estimate the position visually.

• Use a protractor and ruler.

• Use a ruler and compass.

• Use a calculator.

Which tool is essential for determining a 90-degree rotation without a coordinate plane?

• Protractor

• Graph paper

• Calculator

• Compass
