Rotations practice pre algebra 8th grade B
Sure! Here are some practice problems for rotations in pre-algebra:
1. Rotate the point (3, 2) 90 degrees counterclockwise about the origin.
2. Rotate the point (-4, 5) 180 degrees counterclockwise about the origin.
3. Rotate the point (1, -7) 270 degrees counterclockwise about the origin.
4. Find the coordinates of the image of point A(2, -3) after a 90-degree counterclockwise rotation about the origin.
5. Find the coordinates of the image of point B(6, 4) after a 180-degree counterclockwise rotation about the origin.
6. Find the coordinates of the image of point C(-5, 0) after a 270-degree counterclockwise rotation about the origin.
7. Determine whether a rotation of 90 degrees counterclockwise about the origin preserves symmetry for the figure with vertices (2, 3), (5, 6), and (-1, 1). Explain your answer.
8. Determine whether a rotation of 180 degrees counterclockwise about the origin preserves symmetry for the figure with vertices (0, 1), (-1, 2), and (-2, 1). Explain your answer.
9. Determine whether a rotation of 270 degrees counterclockwise about the origin preserves symmetry for the figure with vertices (0, 3), (4, 1), and (2, -2). Explain your answer.
10. Rotate the figure with vertices (1, 2), (4, 3), and (3, 6) 90 degrees counterclockwise about the origin. Find the coordinates of the image vertices.
I hope these practice problems help you improve your understanding of rotations!
