<u>Given </u><u>:</u><u>-</u><u> </u>
<u>To </u><u>prove</u><u> </u><u>:</u><u>-</u><u> </u>
- Sum of interior angles of a ∆ is 180° .
<u>Construction</u><u> </u><u>:</u><u>-</u>
- Draw a line MCN parallel to AB .
- Extend line AB to K .
<u>P</u><u>roof </u><u>:</u><u>-</u><u> </u>
In ∆ ABC , we have ,
As sum of two interior angles of a triangle is equal to the opposite exterior angle .
Also ,
ABC +
CBK = 180°
( linear pair )
Hence from above two ,
<u>Hence </u><u>Proved</u><u> </u><u>!</u><u> </u>
Answer:
the last one
