Given: ABCD is a parallelogram and AP and CQ are perpendiculars from vertices A  and C on diagonal BD.

To prove : \small AP=CQ

Proof: In\small \Delta APB\, \, and\, \, \Delta CQD,

\angleAPB=\angleCQD             (Each 90 \degree)

 \angleABP=\angleCDQ            (Alternate angles)

 AB=CD                (Opposite sides of a parallelogram )

Thus, \small \Delta APB\cong \Delta CQD      (By SAS)

  \small AP=CQ                 (CPCT)
