Question:
Tick (✓) the correct answer:
The sum of all interior angles of a hexagon is
(a) 6 right ∠s
(b) 8 right ∠s
(c) 9 right ∠s
(d) 12 right ∠s
Solution:
(b) 8 right ∠s
Sum of all the interior angles of a hexagon is $(2 n-4)$ right angles.
For a hexagon:
$n=6$
$\Rightarrow(2 \mathrm{n}-4)$ right $\angle \mathrm{s}=(12-4)$ right $\angle \mathrm{s}=8$ right $\angle \mathrm{s}$
