MCQ
The sum of the interior angles of a triangle is:
- A$270^\circ$
- B$360^\circ$
- ✓$180^\circ$
- D$90^\circ$
✓
Answer
Correct option: C.
$180^\circ$
For a triangle,
Number of sides$ (n) = 3$
Sum of interior angles$ = (n - 2) \times 180^\circ $
$= (3 - 2) \times 180^\circ $
$= 1 \times 180^\circ $
$= 180^\circ $
Number of sides$ (n) = 3$
Sum of interior angles$ = (n - 2) \times 180^\circ $
$= (3 - 2) \times 180^\circ $
$= 1 \times 180^\circ $
$= 180^\circ $
