1) Click and Drag the "x" on the geogebra workbook to look at various degrees of rotation.
2) Make note specifically of 90°, 180°, and 270° rotations.
3) You may also move the point of rotation.
Questions:
1) What changes from pre-image to image? What stays the same?
2) 90° rotation: Visualize a segment drawn connecting pre-image to center and another segment connecting image to center. What do you notice?
3) 180° rotation: Visualize a segment drawn connecting pre-image to center and another segment connecting image to center. What do you notice?
4) 270° rotation: Visualize a segment drawn connecting pre-image to center and another segment connecting image to center. What do you notice?
Conclusion:
How could you describe the transformation with precision? What would you need to include?
