Time Narration
00:00 Khublei iaphi baroh . Ngi pdiang sngewbha iaphi sha ka tutorial halor ka Symmetrical Transformation ha ka Geogebra.
00:06 Ha kane ka tutorial ngin pule shaphang ka Symmetrical transformations kum ki:
00:11 Line symmetry,Rotation symmetry
00:13 bad ruh ngin pule ban pynheh ia ki jingdro da ka jingthew bad jaka shong.
00:17 Ngi ngeit ba phi la don ia ka jingtip ban treikam ha ka Geogebra.
00:21 Lada em , na ka bynta ki tutorial ba iadei bad kane , sngewbha leit ha ka website jongngi.
00:26 Ban record ia kane tutorial, Nga pyndonkam da ka Ubuntu Linux OS Version 11.10,
00:31 Geogebra Version 3.2.47.0.
00:35 Ngin pyndonkam da ki Geogebra tools harum:
00:37 Reflect Object about Line
00:39 Rotate Object around Point by Angle
00:42 Dilate object from a Point by Factor
00:45 Semicircle through Two points
00:47 Regular Polygon bad
00:49 Perpendicular bisector
00:51 Ki jingbatai jong ka Transformation-
00:53 Symmetrical transformation jong ka geometric figure ka dei :
00:57 Ka jingkylla ha ka jaka shong ,size lane shape ha ka coordinate plane.
01:02 Ia ka Original figure la khot ka Object.
01:04 Ia ka Transformed figure la khot ka Image.
01:07 Reflection symmetry:
01:09 la khot ruh ia ka kum ka Line symmetry.
01:11 Ka iaid ha ka shi bynta jong ka ka pynpaw ia kawei pat ka bynta .
01:15 Phi lah ban khylliap ia ka dur bad baroh artylli kin ia ryngkat.
01:20 U Line Symmetry u dei u lain ha kaba ia ka dur la pashat.
01:24 To ngin leit sha ka Geogebra window.
01:27 Peit ha Dash home >> Media Apps >> hapoh Type >> jied Education >> bad Geogebra.
01:37 Na bynta kane ka tutorial, ngan khang noh ia ka Algebric view.
01:40 Click ha u jingshon Close ha ka Algebric view.
01:47 To ngin sdang da ka Line of symmetry.
01:50 Nyngkong , to ngin shna ia ka equilateral triangle.
01:53 Jied ia uRegular Polygon tool na u toolbar.
01:57 Click ha u drawing pad points A ,B, bad thep 3 na ka bynta ki jindon jong ki sides.
02:08 Ka equilateral triangle ABC lah dro.
02:11 To ngin dro ia u perpendicular bisector sha kawei ka sides jong ka triangle.
02:15 Jied Perpendicular Bisector Tool bad click ha u side AC.
02:26 Jied ia u Point tool bad shna ia u point hapoh ka triangle.
02:31 Pynkynriah ia u point D sha kawei na ki liang jong ki vertices .
02:38 right click ha u point D bad jied Trace On.
02:43 Jied Reflect Object about Line tool na u tool bar.
02:48 Click ha u point D.Kane kan highlight ia u point D.
02:52 Click ha u Perpendicular Bisector.
02:55 Kane kan pashat ia ka image D dash ha kawei pat ka liang jong u perpendicular bisector.
03:01 D dash kadei ka dur iit khmih jong u point D.
03:04 Buh Trace On na bynta u point D.
03:08 To ngin pynkynriah ia u point D sawdong ka triangle pyndonkam da u Move tool.
03:11 Click ha ka jingjied ba nyngkong hapoh ka Move tool na u toolbar.
03:22 Click ha ka figure bad u mouse.
03:25 Tan ia ka ban trace ia ka triangle .
03:28 Mynta pyllait ia u jingshon u mouse.
03:31 Phi ioh aiu? U perpendicular bisector hangne u dei u lain ka jong ka symmetry.
03:36 D u dei u object bad u D dash kadei ka image.
03:39 To ngin reflect a semicircle about a line.
03:43 To ngin dro ia ka semicircle.
03:44 Click ha ka Semicircle through Two points tool. Buhdak ia u point E bad nangta ia u F.
03:56 Click ha u segment hapdeng artylli ki points.
04:02 Buhdak ia ki points G bad H. Ia u lain la dro.
04:06 To ngin pynkylla ia ka property jong u line.
04:08 Right click ha u lain ,Object Properties. Click ha Style, pynkylla ia ka Style.
