Chapter 14.2, Problem 12CE

To determine

the reflection of line k in the line j

Answer to Problem 12CE

Image of line k in the line j will be, $R_j:line(k)\to k$

Explanation of Solution

Given information: k and j are two line

As the line k andj are perpendicular.

According to theorem 14-2 “A reflection in a line is isometry”, here k is isometric to itself with respect to j .

Therefore,

The image of line k in the line j will be k itself.
