Chapter 8.3, Problem 13E

To determine

The midpoint of line AB.

Answer to Problem 13E

  $EM=MF=\frac{1}{2}EF$

Explanation of Solution

Given:

The given line is:

  

Calculation:

The segment bisector by paper folding will be:

1. Draw the segment EF on a piece on paper.
2. Fold the paper such that point E is on top of point F.
3. Label the midpoint M.

That is,

  

Hence,

  $EM=MF=\frac{1}{2}EF$
