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
00:12	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:

10:21	Shna ia u point hapoh ka pentagon.
10:25	Buh Trace On na bynta u point.
10:27	Phin ioh ia ka reflection jong u point sha shiliang u perpendicular bisector.
10:31	Buh Trace On na bynta ka image point.
10:34	Trace ia ka pentagon ban peit la phi jied ia u lain symmetry ba dei.
10:44	Pynshad ia ka pentagon counter clockwise ba shisha hapoh 135°ha u point.
10:49	Dilate ia ka pentagon ha u point da u factor 3.
10:56	Ka assignment ka dei ban long kumne.
11:03	Peit ia ka video kaba don ha une u URL.

11:12	Ka Spoken Tutorial Project Team : ka pynlong workshops da kaba pyndonkam da ki spoken tutorials.
11:17	Ka ai certificates sha kito kiba pass ha ka online test.
11:20	Ban tip kham bniah , sngewbha thoh sha contact@spoken-tutorial.org.
11:26	KaSpoken Tutorial Project ka dei shi bynta jong ka Talk to a Teacher project.
11:29	La kyrshan ia ka da ka National Mission on Education lyngba ka ICT, MHRD, Sorkar India.
11:35	Khambun ki jingtip ha kane ka Mission ka don ha kane ka link.
