Two sides AB,BC and medium AM of ABC are congruent to the two sides and the median of PQR. Prove ABCPQR

Open in App
Solution

Given:

AM is the median of ABC & PN is the median of PQR.

AB=PQ, BC=QR & AM=PN

Since AM & PN is the median of ABC

12BC=BM & 12QR=QN ------ (AM and PN are median)

Now,

BC=QR ----- (given)

12BC=12QR ------ (Divide both sides by 2)

BM=QN

In ABM and PQN,

AM=PN ------ (Given)

AB=PQ ------ (Given)

BM=QN ------ (Proved above)

ABMPQN ------ (by SSS congruence rule)

B=Q ------ (CPCT)

In ABC and PQR,

AB=PQ ------ (Given)

B=Q ------ (proved above)

BC=QR ----- (Given)

ABCPQR ------ ( by SAS congruence rule)
