Given a regular hexagon, calculate each interior angle of the hexagon

A.
60^{o} 
B.
30^{o} 
C.
120^{o} 
D.
45^{o} 
E.
135^{o}
Correct Answer: Option C
Explanation
Sum of interior angles of polygon = (2n – 4)rt
sum of interior angles of an hexagon
(2 x 6 – 4) x 90^{o} = (12 – 4) x 90^{o}
= 8 x 90^{o}
= 720^{o}
each interior angle will have (frac{720^o}{6})
= 120^{o}
