Question

sides AB,AC and median AD of a traingle ABC are respectively proportional to sides PQ and PR and median PM of another trangle PQR. show that traingle ABC congruent to trangle POR

Answer 1

if the sides proportional then they are equal so in triangle ABC and triangle PQR
AB = PQ
AC = PR
And angle B = angle Q ( equal sides oppposite angles are equal )
∆ ABC=~ ∆ PQR
by SAS congruency
