4: If a point C lies between two points A and B such that AC = BC.

Then prove that AC = 1/2 AB, explain by drawing the figure.

Then prove that AC = 1/2 AB, explain by drawing the figure.

Line AB is drawn by joining A and B and a point C is taken between them such that AC covers the line segment AB in two overlaps.

AB = AC + BC

But, AC = BC,

Therefore, AB = 2AC

i.e., AC = 1/2 AB.
