Question

PLEASE TELL AS EARLY AS POSSIBLE WITH EXPLANATION​

Answer 1

EXPLANATION.

→ Four equal sides BA and CA of ∆ABC

produce to Q and P

→ AP = AQ.

To prove PB = QC.

in ∆PBC and ∆QCB

→ A is the mid point of both the triangle.

→ PC = BQ

→ < B = < C

→ ∆ ABC = ∆ ACQ = ∆ APB

→ by SAS criteria = PB = QC.
