You my use oth sides of one 3 5 rd of notes on the exm onepts to know Tesselltions, reting nd explining: Regulr polygons, tringles, qudrilterls Side lengths, generl nd speifi: 45º-45º-90º tringle nd 30º-60º-90º tringle (nd how to derive them using the Pythgoren Theorem). Working with squre roots Equilterl tringle re nd how to derive for ny equilterl tringle Regulr hexgon re nd how to derive for ny regulr hexgon Properties of, nd re formuls for: Trpezoids, kites, drts, prllelogrms, rhomi, retngles nd squres The four isometries wht re they Find line of trnsltion y mesuring nd onstruting Find line of refletion y mesuring nd onstruting Find enter nd degree of rottion etween two figures y mesuring nd onstruting Perform eh isometry using ompss nd strightedge Given figure nd n imge; determine nd rete the orresponding isometry using no more thn three lines of refletion Sle ftors nd length / perimeter Sle ftors nd re Sle ftors nd volume Rep-tiles nd similrity Pythgoren Theorem visul / lgeri proofs Review questions follow

2 Finl Exm Review Questions 1. rete Venn digrm to lssify the following: Qudrilterl, Prllelogrm, Retngle, Rhomus, Squre, Trpezoid nd Kite. For eh setion of the Venn digrm, drw qudrilterl tht orresponds to tht setion only nd desrie the properties of tht qudrilterl.. Whih regulr polygons rep-tile the plne Explin your nswer. 3. Whih regulr polygons tessellte the plne Explin your nswer. 4. Drw qudrilterl tht does not hve ny prllel sides. Tessellte the plne with this qudrilterl. 5. Is the omposition of two trnsltions ommuttive Why or why not 6. Is the omposition of two refletions ommuttive Why or why not 7. Is the omposition of two rottions ommuttive Why or why not 8. Is the omposition of two glide refletions ommuttive Why or why not 9. The digrm elow represents trnsformtion of to ' '. Whih single motion (rottion, refletion, trnsltion or glide refletion) will move to '. Use ompss nd strightedge to onstrut the omponents of the isometry.. Using no more thn three lines of refletion, mthemtilly show how the motion in prt () n e omplished y sequene of one, two or three refletions (no guess nd hek).
