Question

What is the sum of interior angles a convex polygon having 'n' sides?

• A. $n\times {180}^0$
• B. $(n-1)\times {180}^0$
• C. $(n-2)\times {180}^0$
• D. $(n-3)\times {180}^0$

Answer 1

The correct option is C $(n-2)\times {180}^0$


Generalising the above, the sum of interior angles of a convex polygon with 'n' sides is equal to '$(n-2)\times {180}^{\circ }$'.
