  1. Lesson 5-3 Geometry in Motion

  2. Ohio Content Standards:

  3. Ohio Content Standards: Describe and apply the properties of similar and congruent figures; and justify conjectures involving similarity and congruence.

  4. Ohio Content Standards: Make and test conjectures about characteristics and properties (e.g., sides, angles, symmetry) of two-dimensional figures and three-dimensional objects.

  5. Ohio Content Standards: Draw and construct representations of two- and three-dimensional geometric objects using a variety of tools, such as straightedge, compass and technology.

  6. Ohio Content Standards: Perform reflections and rotations using compass and straightedge constructions and dynamic geometry software.

  7. Ohio Content Standards: Represent and model transformations in a coordinate plane and describe the results.

  8. Ohio Content Standards: Draw the results of translations, reflections, rotations and dilations of objects in the coordinate plane, and determine properties that remain fixed; e.g., lengths of sides remain the same under translations.

  9. Ohio Content Standards: Show and describe the results of combinations of translations, reflections and rotations (compositions); e.g., perform compositions and specify the result of a composition as the outcome of a single motion, when applicable.

  10. Translation

  11. Translation When a figure is slid from one position to another without turning it.

  12. Translation When a figure is slid from one position to another without turning it. Translations are sometimes called “slides”.

  13. Reflection

  14. Reflection When a figure is flipped over a line. The new figure is the mirror image of the original.

  15. Reflection When a figure is flipped over a line. The new figure is the mirror image of the original. Reflections are sometimes called “flips”.

  16. Rotation

  17. Rotation When a figure is turned around a fixed point.

  18. Rotation When a figure is turned around a fixed point. Rotations are sometimes called “turns”.

  19. Identify each motion as a translation, reflection, or rotation.

  20. Identify each motion as a translation, reflection, or rotation.

  21. Identify each motion as a translation, reflection, or rotation.

  22. Identify each motion as a translation, reflection, or rotation.

  23. In the figure, FGHONP by a rotation.

  24. In the figure, FGHONP by a rotation. Name the image of H.

  25. In the figure, FGHONP by a rotation. . . Name the side that corresponds to OP.
