Time Narration
00:01 Khublei iaphi baroh. Ngi pdiang sngewbha iaphi sha kane ka jinghikai/tutorial shaphang ka Theorems on Chords and Arcs in Geogebra.
00:08 Ha kaba kut jong kane ka jinghikai/tutorial,
00:09 phi lah ban pynshisha ia ki theorems shaphang ka :
00:14 Chords jong ka circle.
00:16 Arcs jong ka circle.
00:18 Ngi tharai ba phi lah don ia ki jingtip ba kumno ka Geogebra ka treikam.
