AD is the bisector of angle A of triangle ABC.PQ and PR are perpendiculars from any point lying on AD,P to sides AB and ACrespectively.Show that triangle PQAcongruent to PRA and PQ=PR. Plscheck my answer .
Proof In triangle PQAand PRA
​angleAQP=angleARP(90 degree)
AP=AP(common)
anglePQA=anglePAR
​Therefore triangle PQA congruent to triangle PRA(ASA rule)
2.triangle PQAcongruentto triangle PRA
AQ=AR.
Therefore PQ=PR(By CPCT)
