# State whether following statement is true or false.$\angle AOC=\angle DOB$.

True

##### SOLUTION
Taking line $COD,$
$\Rightarrow$  $\angle AOC+\angle AOD=180^o$               [ Pair of straight line ]     ---- ( 1 )
Taking line $AOB,$
$\Rightarrow$  $\angle AOD+\angle DOB=180^o$                [ Pair of straight line ]           ----- ( 2 )
From ( 1 ) and ( 2 )
$\Rightarrow$  $\angle AOC+\angle AOD=\angle AOD+\angle DOB$
$\therefore$   $\angle AOC=\angle DOB$
