A) \[{{120}^{o}}\]
B) \[{{180}^{o}}\]
C) \[{{45}^{o}}\]
D) \[{{90}^{o}}\]
Correct Answer: D
Solution :
A square has four equal sides. \[\therefore \]Each side subtends the same angle at the centre\[O\]. Let angle subtended be\[{{x}^{o}}\]. So, \[4{{x}^{o}}={{360}^{o}}\] \[\Rightarrow \] \[{{x}^{o}}=\frac{{{360}^{o}}}{4}={{90}^{o}}\]You need to login to perform this action.
