A) AB and CD are perpendicular
B) AB and CD are parallel
C) CD and PQ are perpendicular
D) None of the above
Correct Answer: B
Solution :
\[\angle BPR=\angle DRQ=30{}^\circ \] \[\angle CRQ=\angle APR=150{}^\circ \] \[\angle CRD=\angle APB=180{}^\circ \] Hence, AB and CD are parallel.You need to login to perform this action.
