Chapter 14.2, Problem 16WE

To determine

To draw: pentagon and a line of reflection such that after reflection the same figure is produced

Answer to Problem 16WE

Dotted line is the line of reflection

Explanation of Solution

Given information: after reflection the image is same as previous.

Choose a pentagon with length of all side equal, now taking the mid-point of any of its side, and drawing a line from that point to a vertex opposite to it.

Now using the new line as the line of reflection, the same figure can be obtained, as the two part of the figure are isometric to each other.
