In Theorem 1.5, prove that m(BC bar) = m(AC bar)/2.

Please specify the theorem...If it is like that B lies at the midpoint of line AC than

Length of AB = length of BC

Therefore length of AC = length of AB + length of BC

As AB = BC

Therefore length of AB + Length of BC = 2×Length of BC

Hence length of AC = 2× length of BC

Length of BC= (length of AC)/2

i.e. m(BC) = m(AC)/2
