Questions on Rotation Transformations

1. Basic Definition: What is a rotation in the context of geometric transformations?

2. Center of Rotation: What is meant by the "center of rotation," and how does it affect the outcome of a rotation?

3. Degrees of Rotation: If a triangle is rotated 90 degrees counterclockwise about the origin, what will be the new coordinates of the point (3, 4)?

4. Clockwise vs. Counterclockwise: How do clockwise and counterclockwise rotations differ, and how are they designated in mathematical notation?

5. Rotation Matrix: Write the rotation matrix for a rotation of θ degrees counterclockwise about the origin.

6. Composite Rotations: If a shape is rotated 45 degrees counterclockwise and then another 45 degrees counterclockwise, what is the total rotation?

7. Point of Rotation: If a point (x, y) is rotated 180 degrees about the origin, what are the new coordinates?

8. Rotation and Polygons: A square with vertices at (1, 1), (1, -1), (-1, -1), and (-1, 1) is rotated 90 degrees counterclockwise about the origin. What are the coordinates of the vertices after the rotation?

9. Negative Rotations: How would a rotation of -90 degrees about the origin affect the point (2, 3)?

10. Rotation Around a Point: How would you perform a rotation of 120 degrees around the point (1, 2) for the point (3, 4)? Describe the steps.

11. Effects on Shapes: Does a rotation change the size or shape of a geometric figure? Explain your reasoning.

12. Final Position: After rotating a point (5, -2) by 270 degrees counterclockwise about the origin, what is the final position of the point?

13. Visualizing Rotation: How would you draw the trajectory of a point as it undergoes a 180-degree rotation about the origin?

14. Applications of Rotation: Describe a real-world example where rotation might be used in design or engineering.

15. Inverse Rotation: If a point is rotated 150 degrees about the origin, what angle would you use to rotate it back to its original position?
