Understanding Rotations

What is the direction of a clockwise rotation?

• To the left

• To the right

• Downwards

• Upwards

What happens to the radius of a circle during a rotation?

• It disappears

• It remains the same

• It decreases

• It increases

What remains unchanged during a rotation?

• The texture of the figure

• The position of the figure

• The color of the figure

• The size and shape of the figure

What is the center of rotation in a figure?

• A point that moves

• A fixed point

• A point that changes shape

• A point that changes size

What is the effect of a rotation on the congruency of a figure?

• It changes texture

• It remains congruent

• It changes color

• It becomes non-congruent

How many degrees does a full rotation cover?

• 270 degrees

• 360 degrees

• 180 degrees

• 90 degrees

How do you describe a rotation of 180 degrees?

• A flip of x and y coordinates

• A change in shape

• A change in size

• A reversal of signs of both coordinates

What is the result of a 90-degree clockwise rotation of point (x, y)?

• (x, y)

• (y, -x)

• (-y, x)

• (-x, -y)

What is the equivalent of a 270-degree counterclockwise rotation?

• 180-degree clockwise

• 360-degree clockwise

• 90-degree clockwise

• 270-degree clockwise

What is the new position of point (2, 5) after a 90-degree clockwise rotation?

• (5, -2)

• (-5, 2)

• (2, -5)

• (-2, 5)
