            ((AD)/2)=1=OA=OC=AC=PC      ((AB)/(AC))=((PQ)/(PC))⇔((AB)/1)=((PQ)/1)=sin(30°)=(1/2)⇔                              AB=PQ=(1/2)

$$\:\:\:\:\:\:\:\:\:\:\:\:\frac{{AD}}{\mathrm{2}}=\mathrm{1}={OA}={OC}={AC}={PC} \\ $$$$\:\:\:\:\frac{{AB}}{{AC}}=\frac{{PQ}}{{PC}}\Leftrightarrow\frac{{AB}}{\mathrm{1}}=\frac{{PQ}}{\mathrm{1}}={sin}\left(\mathrm{30}°\right)=\frac{\mathrm{1}}{\mathrm{2}}\Leftrightarrow \\ $$$$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:{AB}={PQ}=\frac{\mathrm{1}}{\mathrm{2}} \\ $$$$ \\ $$
