Rotate each point counterclockwise about the origin on a coordinate grid.
Use prime notation to write the coordinates of its rotation.
- A(2, 7), 90° 2. B(5, 3), 180° 3. C(4, 11), 270°
- D(6, 1), 90° 5. E(0, 5), 180° 6. F(8, 0), 270°
Use the given graph for exercises 7–9.
- Give the coordinates of the
vertices of triangle ABC. - Give the coordinates of the
rotation image of triangle ABC. - Describe the rotation of triangle
ABC.
Graph each figure and its image on the same coordinate grid.
Then describe its rotation.

Graph each triangle and its image on the same coordinate grid.
Use prime notation to write the coordinates of its rotation.
