Question

ifPQ equal to QR angle X is equals to angle Y prove that ar is equals to PB ​

Answer 1

Answer:

set up your proof like this:

Statements | Reasons

PQ=QR |Given

m<x=m<y | Given

m<PQR=m<RQP | Reflexive Property

ΔPQB ≅ ΔRQA | ASA

(Technically you should put a step here saying line AR is congruent to line PB by CPCTC. This would make the reasons for the next step that congruent lines have equal measures.)

AR = PB | CPCTC (Corresponding Parts of Congruent Triangles are Congruent)
