Transformations: Guided Notes Embedded IXL pre-requisite skill practice: A1, 01, 02, 03, and 04 1. Transformations as Functions A. input ordered pairs output independent dependent f ( x ) 1. In algebra (and perhaps science) class, you learned that functions needed an variable, the x, to use as the of a number into an expression. 2. When the expression was simplified, you worked with the equation to determine the variable, or y. 3. was sometimes denoted as 4. You learned that x was paired with only one y in a function. 5. You completed tables and used the to plot points, which became lines, parabolas, etc. B pre-image image congruent angles segments non-rigid distance shape size lengths measures dilations rotations reflections translations corresponding 6. A transformation has a specific meaning in geometry. A transformation is a function that assigns to each point of the plane a matching or point. 7. Transformations that preserve lengths of and measures of_ are called rigid transformations. 8. The three rigid transformations are and 9. The beginning figure (or given figure) is called the 10. The resulting figure determined by the transformation is called the 11. Rigid transformations will preserve and of the original figure. 12. Because of this preservation, the pre-image and image will be 13. Non-rigid transformations preserve angle but not side
