  1. TWO The butterfly and fan below illustrate the two kinds of symmetry. Reflection, Mirror, or Line Symmetry Rotational Symmetry

  2. Reflection and Rotation Symmetry Reflection and Rotation Symmetry Neither Rotation Nor Reflection Reflection Symmetry http://www.teachertube.com/view_video.php?viewkey=415654200fc3faa05828

  3. Reflection, Rotation, Translation We all know that we see our "reflection" in a mirror. If I draw a triangle on the board and this "mirror," what would the reflection look like? http://www.teachertube.com/view_video.php?viewkey=9049907919279f29bd9d

  4. Reflection, Rotation, Translation If I make an "X" on this line on the original triangle, where would it be on the reflected triangle? Well, when we reflected the triangle, we sort of flipped it over that "mirror," or the line, so it would be on the opposite side of the triangle, like this:

  5. Reflection, Rotation, Translation To rotate an object, you just turn it. It is like putting the object on a plate, and then spinning the plate around while the plate's center stays in one place.

  6. Reflection, Rotation, Translation To translate an object, you just move it. You slide it over a certain distance.

  7. Reflection, Rotation, Translation Examples To rotate 90° clockwise use the formula (b, ⁻a) or (y, ⁻x)
