In Question 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"`).
Point C is called a mid-point of line segment AB. Prove that every line segment has one and only one mid-point.

Explanation

To prove that if a point C lies between two points A and B such that AC = BC, then AC = 1/2 AB, and to show that every line segment has one and only one midpoint, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Given Information**:
- We have three points: A, B, and C.
- Point C lies between points A and B.
- It is given that AC = BC.
