    3d transformations 3d transformations Presentation Transcript

    • 3d: Perform transformations (rigid and non-rigid motions) on two-dimensional figures using the coordinate plane (DOK 2)
      By: Deia Sanders
    • Experiment
    • Vocabulary
      Transformation: a transformation is a translation (sometimes called a slide), a reflection (sometimes called a flip), a rotation (sometimes called a turn), or a dilation (sometimes called an enlargement or reduction)
      Translation: a translation is the figure resulting from moving every point of a given figure a certain distance in a certain direction
    • More Vocabulary
      Reflection: a figure is said to be reflected with respect to a line if a fold on the line makes the two figures coincide
      Rotation: a translation that moves the figure in a clockwise or counterclockwise direction with respect to a specific point
      Dilation: enlargement or reduction in the polygon; the polygons are similar
    • Let’s look at some examples!
      Turn to pages 180- 184
    • Turn to Handout #1
      • Draw a figure in quadrant 2
      • Reflect 5 places to the right and 2 places down.
      • Rotate it 90 degrees clockwise
    • Day 2
      3d: Perform transformations (rigid and non-rigid motions) on two-dimensional figures using the coordinate plane (DOK 2)
    • Turn to Handout #1
      • Draw your first initial in block letters in quadrant I
      • Label the coordinates of each vertex
      • Sketch the translation across the x-axis (slide, not reflect). Label the coordinates and vertices.
      • Translate your initial 4 units to the left and 2 units up. Label the coordinates and vertices.
      • Check your neighbors work
    • Classwork
      Complete Handout #2
      page 196
      (you may want to use remaining graphs in Handout #1 to complete)
    • Day 3
      3d: Perform transformations (rigid and non-rigid motions) on two-dimensional figures using the coordinate plane (DOK 2)
    • Let’s Review Vocabulary
      Transformation
      Translation
      Reflection
      Rotation
      Dilation
    • Review
