Question

In a triangle abc, p and q are the middle points of the sides ab and ac respectively. r is a point on the segment pq such that pr : pq = 1:2 . if pr = 2 cm, then bc=?

Answer 1

hey bro this comes directly from a theorem
and the answer will be 8
pr = 2 as pr/pq=1/2 =>pq=4cm
then bc = 2 × pq=8cm
