| 07:10 | Kum ka assignment, Nga kwah iaphi ba phin draw/dro ia ka triangle ABC. |
| 07:15 | Mark ia u point D ha u BC, pyniasoh ia u AD. |
| 07:19 | Draw/dro ia ka incircles na ka triangles ABC, ABD bad CBD jong ka radii r, r1 bad r2 . |
| 07:28 | BE u dei u height 'h'. |
| 07:30 | Pynkhih/Move ia ki vertices jong ka triangle ABC, |
| 07:33 | ban pynshisha ia ka jingiadei relation: |

| 07:43 | Ka output jong ka assignment ka dei ban long kumne. |
| 07:52 | Peit ia ka video kaba lah ban ioh na kane ka URL. |
| 07:55 | Ka pynlyngkot ia ka Spoken Tutorial project. |
| 07:57 | Lada phim don ia ka bandwidth kaba biang, phi lah ban download bad peit ia ka. |
| 08:02 | Ka Spoken Tutorial Project Team : ka pynlong ia ka workshops da kaba pyndonkam da ka spoken tutorials. |
| 08:06 | Ka ai certificates ia kito kiba pass ia ka online test. |
| 08:09 | Ia ki jingtip ba kham bniah , contact ia ngi ha ka contact@spoken-tutorial.org. |
| 08:16 | Ka Spoken Tutorial Project kadei ka bynta jong ka jingkren sha ki nonghikai project. |
| 08:19 | La kyrshan ia ka da ka National Mission on Education lyngba ka ICT, MHRD, Government jong ka India. |
| 08:25 | Ia ki jingtip ba kham bniah ha kane ka mission lah ban ioh na kane ka link. |
| 08:29 | Ine i dei i Ribajanai na Meghalaya, signing off. Khublei ba phi lah iasoh. |
