We proceed to present the demonstration of the following proposition:
<em>If Y is the midpoint of XZ, then XY = 1/2 XZ.</em>
1) Y is the midpoint of XZ. Given.
2) Definition of line segment.
3) By 1)
4) 3) in 2)
5) Algebra/Result
Therefore, the proposition <em>If Y is the midpoint of XZ, then XY = 1/2 XZ </em>is true.
