The bisectors of BandC of a quadrilateral ABCD intersect in P. Show that P is equidistant from the opposite sides AB and CD.

Solution

In ΔPMC and ΔPXC,

PMC=PXC (perpendiculars)

PCM=PCX ( bisectors of \angle DCB)

CP = CP(common side)

ΔPMCΔPXC (by AAS congruence)

Hence by cpct

PM = PX ........ (1)

Now in ΔPNB and ΔPXB,

PNB=PXB (perpendiculars)

PBN=PBX (bisectors of CBA)

BP = BP(common side)

ΔPNBΔPXB (by AAS congruency)

Hence by cpct

PN = PX........ (2)

From (1) and (2) PM = PN

Hence P is equidistant from the opposite sides AB and CD
