Question

Assertion (A): The SSS criterion is sufficient to prove the similarity of two triangles. Reason (R): All corresponding angles will be equal if the sides are proportional.

Assertion (A): In ΔPQR and ΔXYZ, if PQ/XY = QR/YZ = RP/ZX, then ΔPQR∼ ΔXYZ Reason (R): The SSS similarity criterion uses the equality of angles.

If in two triangles ABC and PQR, AB/QR = BC/PR = CA/PQ, then :

The sides AB, BC and median AD of a ∆ABC are respectively propotional to the sides PQ, QR and the median PM of ∆PQR. Show that ∆ABC ~ ∆PQR.
