Exploring Geometry Rotations: 90°, 180°, 270°, and 360°

What does a rotation in geometry refer to?

• A change in color

• A change in orientation

• A change in position

• A change in size

What is a 90-degree rotation equivalent to?

• Half turn

• Quarter turn

• Full turn

• Three-quarter turn

After a 180-degree rotation, a point's new location is independent of rotation direction.

• Depends on the rotation speed

• True

• False

• Depends on the point's original quadrant

What does the capital R notation signify in geometry?

• Reflection

• Rotation

• Repositioning

• Resizing

What does a negative degree of rotation indicate?

• Counterclockwise movement

• Random movement

• No movement

• Clockwise movement

What is the result of rotating a point 270 degrees counterclockwise?

• It returns to its original position

• It moves to the opposite quadrant

• It completes three-quarter turns

• It remains in the same quadrant

How are clockwise rotations represented in terms of degrees?

• Positive values

• Negative values

• It varies

• Zero

Which of the following is a correct rotation rule for a 90-degree counterclockwise rotation?

• -Y becomes X, X becomes -Y

• X becomes Y, Y becomes -X

• -Y becomes X, X becomes Y

• Y becomes X, -X becomes Y

After rotating a line segment 90 degrees clockwise, what happens to its orientation?

• It remains unchanged

• It becomes perpendicular to the original

• It becomes diagonal to the original

• It becomes parallel to the original

A positive 180-degree rotation of a figure results in:

• The figure returning to its original position

• The figure moving to a new position

• The figure's size changing

• The figure's orientation being reversed
