(i) AB = BC, m is the mid point of AB and n is the mid point of BC. Show that AM = M C
(ii) BM = BN , M is the mid point of AB and N is the midpoint of bc show that AB = BC

Dear Student,

Please find below the solution to the asked query:

i ) Given : AB = BC, M is the mid point of AB and N is the mid point of BC. 

From Euclid's 7^th axiom we know " Things which are halves of same things are equal to one another . "

So,

$\frac{\mathrm{AB}}{2} = \frac{\mathrm{BC}}{2}$

AM = NC                                                               ( Hence proved )

ii ) Given : BM = BN, M is the mid point of AB and N is the mid point of BC. 

From Euclid's 6^th axiom we know " Things which are double of the same things are equal to one another . "

So,

2 BM =  2 BN

AB = BC                                                               ( Hence proved )
