Read each question carefully and follow the instructions to perform rotations or identify rotation properties.
1. What is a rotation in geometry? Describe its key characteristics.
2. A 90-degree clockwise rotation about the origin transforms a point (x, y) to the point .
3. A 180-degree rotation about the origin transforms a point (x, y) to the point .
4. A 270-degree clockwise rotation about the origin transforms a point (x, y) to the point .
5. Which rotation rule transforms the point A(2, 5) to A'(-5, 2)?
90° clockwise rotation
90° counter-clockwise rotation
180° rotation
270° clockwise rotation
6. Plot the triangle with vertices A(1, 2), B(4, 2), and C(1, 5) on the graph below. Then, rotate the triangle 90 degrees counter-clockwise about the origin and label the new vertices A', B', C'.
Write the coordinates of the rotated triangle:
A' =
B' =
C' =
