If the length of AC=12, BC=8,then the length of AB will be 4 units.
Given that the length of AC=12, BC=8.
We are required to find the length of AB which is the missing segment of the line AC.
Line segment is the collection of the points that lies on the surface.
B is not the mid point of the line AC. We can use the combination of the lengths.
AC is the line and AB is part of the line, so
AC=AB+BC
12=AB+8
AB=12-8
AB=4 units
Hence if the length of AC=12, BC=8,then the length of AB will be 4 units.
