Time Narration
00:00 Khublei iaphi baroh.
00:01 Bad ngi pdiang sngewbha iaphi sha kane ka spoken tutorial/jinghikai shaphang ka Relationship between different Geometric Figures in Geogebra.
00:07 Ngi tharai ba phi lah don ka jingtip ia ka jingtreikam jong ka Geogebra.
00:11 Lada em , sngewbha leit lyngba ka Introduction to Geogebra tutorial/jinghikai shwa ba phi iaid shaphrang.
00:18 Sngewbha peit ba ka jingthmu ban hikai ia kane ka jinghikai kam dei ban bujli ia u compass box ba shisha.
00:24 Ka jingtei hapoh ka Geogebra ka lah pyndep bad ka view ban sngewthuh ia ki properties.
00:29 Hapoh kane ka jinghikai , ngin pule ban construct/tei ia ka
00:32 cyclic quadrilateral bad incircle.
00:35 Ban record ia kane ka jinghikai , Nga pyndonkam da ka Linux operating system
00:39 Ubuntu Version 10.04 LTS
00:43 bad Geogebra Version 3.2.40.0.
00:48 Ngin pyndonkam da ki Geogebra tools kiba harum na bynta ka jingtei/construcion:

Compass, Segment hapdeng ki Points, Circle bad ka Center lyngba u Point, Polygon, Perpendicular Bisector, Angle Bisector bad Angle.

01:02 Shah ngin bujli sha ka Geogebra window kaba thymmai.
01:05 Ban leh ia kane, shah ngin nion ha ka Applications, Education bad Geogebra.
01:13 Shah ngan resize ia kane ka window.
01:18 Nion ha u Options menu, nion ha Font Size bad hadien kata ha u 18 point ban shna ia ka figure/dur kaba shai.
01:25 Shah ngin tei/construct ia ka cyclic quadrilateral.
01:27 Ban leh ia kane , shah ngin jied ia ka Regular Polygon tool na u tool bar, nion ha ka Regular Polygon tool, nion ha uwei na artylli ki points ha u drawing pad.
01:38 Ngi iohi ba ka dialog box ka plie/open bad u default value 4.
01:42 Nion OK.
01:43 Ka square ABCD ka draw/dro.
01:46 Shah ngin pynthiah shiliang/tilt ia ka square da kaba pyndonkam da ka Move tool kaba don ha ka kamon.
01:51 Jied ia u Move tool na u tool bar, nion ha u Move tool.
01:56 Buh ia u mouse pointer ha u A lane ha u B. Ngan jied ia u B.
02:01 Buh ia u mouse pointer ha u B bad drag ia u bad u mouse. Ngi iohi ba ka square ka don ha ka kyrdan/position kaba thiah shiliang/titled mynta.
02:10 Let's construct a perpendicular bisector to the segment AB.
02:15 Ban leh ia kane , shah ngin jied ia ka Perpendicular Bisector tool na u tool bar.
02:20 Nion ha ka Perpendicular Bisector tool.
02:22 Nion ha u point A
02:24 Bad hadien kata ha u pointB.
02:26 Ngi iohi ba ka perpendicular bisector ka lah draw/dro.
02:30 Shah ngin construct/tei ia ka perpendicular bisector kaba ar sha u segment BC. Ban leh ia kane,
02:36 jied Perpendicular Bisector tool na u tool bar, nion ha u Perpendicular Bisector tool.
02:42 Nion ha u point B
02:44 bad hadien kata ha u point C.
02:46 Ngi iohi ba ka perpendicular bisectors ka ia kynduh ha u point.
02:50 Shah ngin mark ia une u point kum u E.
02:54 Shah mynta ngin construct/tei ia ka circle bad ka centre kum u E bad kaba pass lyngba u C.
03:01 Shah ngin jied ia ka Circle with Centre through Point tool na u tool bar, nion ha ka Circle with Centre through Point tool.
03:09 Nion ha u point E kum ka centre bad kaba pass lyngba u C. Nion ha u point E bad hadien kata ha u point C.
03:18 Ngi iohi ba ka circle kan pass lyngba baroh ki vertices jong ka quadrilateral. Ka cyclic quadrilateral ka lah draw/dro.
03:29 Phi tip ba ka cyclic quadrilateral ka don maximum area ha pdeng baroh ki quadrilaterals jong ka sequence ba ia kajuh jong ka side lengths?
03:37 Shah ngin pyndonkam da ka Move tool, ban animate/pynim ia ka figure/dur.
03:42 Ban leh ia kane, shah ngin jied ia ka Move tool na u tool bar, nion ha ka Move tool.Buh ia u mouse pointer ha u A lane B. Ngan jied ia u A.
03:52 Buh ia u mouse pointer ha u A bad drag ia u bad u mouse ban animate/pynim,
03:58 ban pynshisha ba ka jingtei/construction ka dei.
