help me plz..
first mark it as brainliest I'm giving u the solution
Given that C is the lies between both points A and B
And
AC����� = BC
Add AC both side we get
AC� + AC� ���� = BC + AC

According to definition of Euclid , if equals are added to equals, whole will equal�
Here, (BC + AC) coincides with AB. It is known that things which coincide with one another are equal to one another.
2AC� � = AB�
Divide by 2 we get
AC� ��� = AB/2
And
AC����� = BC
Add AC both side we get
AC� + AC� ���� = BC + AC

According to definition of Euclid , if equals are added to equals, whole will equal�
Here, (BC + AC) coincides with AB. It is known that things which coincide with one another are equal to one another.
2AC� � = AB�
Divide by 2 we get
AC� ��� = AB/2
