A) \[{{45}^{o}}\]
B) \[{{60}^{o}}\]
C) \[{{75}^{o}}\]
D) \[{{90}^{o}}\]
Correct Answer: D
Solution :
Given OP is a ray on line QR. Also \[\angle POQ=\angle POR.\] \[\angle POQ=\angle POR\] ?..(i) \[\angle POQ+\angle POR={{180}^{o}}\] ?..(ii) From (1) and (2), we have \[2\angle POQ={{180}^{o}}\] \[\Rightarrow \] \[\angle POQ=\frac{{{180}^{o}}}{2}={{90}^{o}}\]You need to login to perform this action.
