Presentation Transcript

  1. Geometry: Transformations MCC1: a. Describe three-dimensional figures formed by translations and rotations of plane figures through space.

  2. Essential Questions: • How can the coordinate plane help me understand properties of reflections, translations and rotations? • What is the relationship between reflections, translations and rotations?

  3. Transformations A transformation is a way to move all the points on a figure. Types of Transformations: • Translations • Reflections • Rotations • Dilations

  4. Translation A translation is a transformation that SLIDES a figure across a plane or through space. All points of the figure move the same distance in the same direction.

  5. Translation We will also learn how to translate figures on a coordinate plane! How was this figure translated?

  6. Translation

  7. Reflection A reflection is a transformation in which a figure is FLIPPED across a line. The line is called a line of reflection. After a figure is reflected, it looks like a mirror image of itself.

  8. Reflection We will also learn how to reflect figures on a coordinate plane! How was this figure reflected?

  9. Reflection

  10. Rotation A rotation is a transformation that TURNS a figure about a point.

  11. Rotation

  12. Rotation How was this figure rotated? We will also learn how to rotate figures on a coordinate plane!

  13. Dilation A dilation is a transformation in which a figure GROWS or SHRINKS. The size of the figure changes, but the shape doesn’t!

  14. Dilation How was this figure dilated? We will also learn how to dilate figures on a coordinate plane!

  15. Dilation
