The document is notes from a student's notebook about an investigation assignment that is due the next day. It reviews different types of geometric transformations including reflections, rotations, translations, dilations, and contractions. It provides examples of problems from pages 342 through 345 that involve applying these transformations to graphs. The student is to complete problems 11 through 14 from page 345 for the assignment.

Investigation #5:
REVIEW-->
*transformations - the changing of a figure's position or form.
*reflection - a "flip" - oftentimes over either the x-axis or the y-axis
*rotation - a "turn" on a certain point - oftentimes the rotation
happens in 90 degree increments
*translation - a "slide" - oftentimes both a horizontal shift & a
vertical shift (4, 2)--means 4 units to the right and up 2 units

*dilation - an enlargment of a figure
scalefactor
*contraction - a reduction of a figure
FYI...to complete a dilation or a contraction on a figure - multiply
the coordinates of the figure by the scale factor to get the
coordinates of the new figure
