Question

in triangle abc,e and f are the midpoint of ab and ac respectively. if ef =5 then find bc​

Answer 1

Answer:

by midpoint theorem , EF||BC and EF =1/2BC

5 = 1/2 BC

BC = 5x2 = 10 cm

Answer 2

Answer:by mid point theorem if we join EF, EF will be parallel to BC and will be 1/2 of BC . Therefore BC =2*EF =2*5=10
