To determine

To find: the result of this section does this illustrate.

Explanation of Solution

Given information:

Cut out any large $\Delta XYZ$ . Fold so that $X$ lies on the fold line and $Y$ falls on $\overrightarrow{YZ}$ . Let $P$ be the intersection of $\overrightarrow{YZ}$ and the fold line. Unfold. Now it fold the paper so that $Y$ coincides with $P$ . Fold it twice more so that both $X$ and

  $Z$ coincide with $P$ .

  

Calculation:

Cut out any large $\Delta XYZ$ .

Fold so that $X$ lies on the fold line and $Y$ falls on $YZ$ .

Consider that $P$ be the intersection of $YZ$ and the fold line. Unfold.

Fold the paper $Y$ coincides with $P$ . Fold it twice more both $X$ and $Z$ coincide with $P$ .

  

It is clear from the figure that after folding each point coincides with $P$ .

The figure will be visible as shown below, it looks like right angle triangle.
