|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''',

|-
|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
