Question

Two sides AB and BC and median AM triangle ABC are respectively equal to sides PQ and QR and median PN of APQR Show that: (i) AABM = APQN (ii) AABC = APQR ​

Answer 1

Answer:

if there are two line parallel and any chord is intersecting it

it means that they are

Explanation:

Answer 2

$\huge\frak{\blue{Answer}}$

△ABC and△PQR in which AB=PQ,BC=QR and AM=PN.

Since AM and PN are median of triangles ABC and PQR respectively.

Now, BC=QR

Given

⇒ ½ BC= ½QR

Median divides opposite sides in two equal parts

BM=QN... (1)

Now, in △ABM and△PQN we have

AB=PQ ∣ Given

BM=QN ∣ From (i)

and AM=PN ∣ Given

∴ By SSS criterion of congruence, we have

△ABM≅△PQN, which proves (i)

∠B=∠Q ... (2) ∣ Since, corresponding parts of the congruent triangle are equal

Now, in △ABC and△PQR we have

AB=PQ ∣ Given

∠B=∠Q ∣ From (2)

BC=QR ∣ Given

∴ by SAS criterion of congruence, we have

△ABC≅△PQR, which proves (ii)
