Time Narration
00:00 Khublei iaphi baroh. Ngi pdiang sngewbha iaphi sha kane ka tutorial/jinghikai halor ka Mensuration in Geogebra.
00:06 Ha kane ka tutorial/jinghikai , ngin pule kumno ban wad ia ka:
00:09 Area bad perimeter jong ka rhombus
00:12 Surface area jong ka sphere bad cone
00:15 Volume jong ka sphere bad cone.
00:20 Ngi tharai ba phi lah don ia ka jingtip kumno ka Geogebra ka treikam.
00:24 Na bynta ka tutorial/jinghikai ba iadei ha ka Geogebra,
00:27 sngewbha leit ha ka website ka jong ngi.
00:31 Ban record ia kane ka tutorial/jinghikai , Nga pyndonkam da ka:
00:33 Ubuntu Linux OS Version 11.10
00:38 Geogebra Version 3.2.47.0
00:42 Ngin pyndonkam da ki Geogebra tools kiba harum:
00:46 Segment between two points
00:48 Circle with center and radius
00:51 Ellipse
00:52 Polygon
00:54 New point bad
00:56 Insert text
00:57 To ngin plie/open ia ka Geogebra window kaba thymmai.
01:00 Click ha Dash home bad Media Apps. Hapoh Type, jied Education bad Geogebra
01:13 To ngin wad ia ka area jong ka rhombus.
01:15 To ngin pyndonkam da ka file quadrilateral.ggb jong ka tutorial/jinghikai kaba la dep.
01:20 Click ha File, Open, Click ha quadrilateral.ggb.
01:27 Click ha Open.
01:29 Ka Area jong ka Rhombus =1/2 * product of diagonals. [is equal to half the product of diag]
01:34 Ban pyni ia ka:
01:36 Click ha ka Insert Text tool.
01:39 Click ha u drawing pad.

Ka text box ka open/plie.

01:44 Area of the rhombus =+(1/2 g f)

Open/Plie ia ki double quotes(“), type:

Area of the rhombus = khang ia ki double quotes

+ na bynta ban pyniasoh . open/plie ia ki brackets, type:

1by/2 space f space g

Close/khang ia ki bracket

f bad g ki dei ki diagonals jong ka rhombus.

02:09 Click OK.
02:11 Ka Area jong ka rhombus la pyni hangne ha u drawing pad.
02:14 Kaba bud, to ngin wad ia ka perimeter.
02:17 Click ha ka Insert text tool.
02:19 Click ha u drawing pad. Ka text box ka open/plie.
02:22 Open/Plie ia ki the double quotes(“) type:

Perimeter of the rhombus =+(4 a)

Close/khang ia ki double quotes '+' open/plie ia ki brackets

4 space 'a' close/khang ia ki brackets

a u dei u side jong ka rhombus.

02:44 Click OK.
02:46 Ka Perimeter jong ka rhombus la pyni hangne ha u drawing pad.
02:50 To mynta ngin save ia ka file.
02:53 Click ha ka File bad Save As.
02:55 Ngan type ia ka filename kum ka rhombus-area-perimeter
03:12 click ha Save.
03:17 Kum ka assignment, Nga kwah ia phi ban wad ia ka area bad perimeter jong ka trapezium,
03:22 pyndonkam da ka output jong ka file cons-trapezium.ggb.
03:27 Rename ia ka object g sha u b.
03:30 Ka Formula na bynta ka area = (half sum of parallel sides) * (vertical height) = (a+b)/2* h
03:40 Ka Formula na bynta ka perimeter =(sum of the sides) =(a+b+c+d)
03:49 Ka output jong ka assignment ka dei ban long kumne.
03:54 To ngin plie ia ka Geogebra window kaba thymmai ban draw/dro ia ka sphere.
03:58 Click ha File , New
04:01 Click ha ka Circle with Center and Radius tool, na u toolbar.
04:06 Click ha u drawing pad point A.

Ka text box kaplie.

04:11 Thoh ia u value 2 na bynta ka radius.
04:13 Click OK.
04:15 Ka circle bad ka center A bad radius 2cm la draw/dro.
04:19 Jied New point tool na u tool bar, mark ia u point B ha ka circumference jong ka circle.
04:26 Jied Segment between two points tool.
04:29 Pyniasoh ia ki points A bad B kum ka radius jong ka circle.
04:34 to ngin draw/dro ia ka ellipse CDE hapoh ka horizontal direction,

Ban ktah ia ka circumference jong ka circle.

04:42 Click ha Ellipse tool.
04:45 Mark ia ki points C bad D diagonally/ba pom pynkiang mar pyrto uwei ia uwei ha ka circumference

Bad u point ba lai u E hapoh ka circle.

04:56 Hangne ia ka sphere la draw/dro.
04:59 to mynta ngin wad ia ka Surface area jong ka sphere.
