In Fig. 14.96, M, N and P are mid points of AB, AC and BC respectively. If MN=3 cm, NP=3.5 cm and MP = 2.5 cm, calculate BC, AB and AC.

Given,

M, N, P are mid points AB, AC and BC

MN = 3cm

NP = 3.5cm

MP = 2.5cm

MN =

BC = 2MN = 2×3 = 6cm

MP =

AC = 2MP = 2×2.5 = 5cm

AP =

AB = 2AP = 2×3.5cm
