# Which of the following is not an obtuse angle ?

$\displaystyle { 182 }^{ o }$

##### SOLUTION
Obtuse angle lies between $\displaystyle { 90 }^{ o }$ to $\displaystyle { 180 }^{ o }$ and $\displaystyle { 182 }^{ o }$ is a reflex angle, so it is not a obtuse angle.
Acute angle is the angle which is greater than $\displaystyle { 0 }^{ o }$ and less than $\displaystyle { 90 }^{ o }$.
Obtuse angle is the angle which is greater than $\displaystyle { 90}^{ o }$ and less than $\displaystyle {180 }^{ o }$.
Right angle is the angle which is equal to $90^o$.
Reflex angle is the angle which is greater than $\displaystyle {180}^{ o }$ and less than $\displaystyle {360 }^{ o }$.
