4. If a point C lies between two points A and B such that AC = BC, then prove that AC =1/2AB. Explain by drawing the figure.
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
Hence proved
