• 3.10 Lesson Name (print first and last) _____________________________________ Per_____ Date: 10/29 due 10/31 3.10 Rigid Transformations: Sequence of Transformations Geometry Regents 2013-2014 Ms. Lomac SLO: I can perform a sequence of transformations on a given figure using a straightedge and compass and explain how and why the construction of the sequence results in the final image. (1) R is the midpoint of ST . Answer each question about the diagram. (a) When S is rotated 180 around R it maps to point T because . . . _______________________________________________________________________ (b) When N is rotated 180 around R it maps to point U because . . . _______________________________________________________________________ (c) SN TU because . . . ________________________________________________________________________________ (d) Do you think NSR UTR ? _______ because. . . ________________________________________________ _________________________________________________________________________________________________. (2) Construct each transformation

(a) Rotate M 90 around point E (RE, 90 ) (b) Reflect point H across line m. (rm) (c) Translate point Q along vector VA ( TVA )

(3) In problem 2, there are abbreviations for each transformation in parentheses. Write out what each transformation abbreviation means below.

• 3.10 (4) A sequence or composition of transformations is when a figure undergoes multiple transformations. Describe each composition of transformations below using the terms reflection, rotation, and translation. Estimate degrees of a rotation and direction and distance of a translation. (a) (b) (c) (d)

(5) Reading and writing transformations. (a) Descriptions of compositions of transformations are stated:

The reflection across line m of a translation along vector AB of point Q. Which do you think happens first, the reflection, or the translation? _____________________ because __________

Anthony took a picture of the drawing of his family. Which do you think happens first, the picture or the drawing? ___________________ because _______________ ____________________________________________________________________________________________ (c) Read the sentence from part (a) again.

The reflection across line m of a translation along vector AB of point Q. Which happens first, the reflection, or the translation? _____________________ Did your answer change? ______ Why/why not? ________________________________________________________________________________

(6) Compositions of transformations are written THA RC ,45 (YZ ). This is read the transformation along vector HA of the rotation 45 around point C of segment YZ. Based on your work in problem #5, Which happens first, the translation or the rotation? _____________________________ because __________________________________________________ ____________________________________________________________________________________________

• 3.10 (7) Use the abbreviation examples from problem #3 and the order of compositions from #5 & #6 to describe each composition of transformations and then write the abbreviation for it. (a) Abbreviation: ________________________________

(b) Abbreviation: ________________________________

Description: ________________________________________________ __________________________________________________________ __________________________________________________________

(8) Describe with as much detail as possible the composition of transformations that map PQR to XYZ. You may want to add letters to the in-between steps to make your explanation easier. _________________________________________________________________________________________________. _________________________________________________________________________________________________. _________________________________________________________________________________________________. _________________________________________________________________________________________________. _________________________________________________________________________________________________. _________________________________________________________________________________________________. _________________________________________________________________________________________________. _________________________________________________________________________________________________. _________________________________________________________________________________________________. _________________________________________________________________________________________________.
