Chapter 14.2, Problem 8CE

To determine

To find: the reflection of $\angle STU$

Answer to Problem 8CE

The reflection of $\angle STU$ is,

  $R_K:\angle STU\to \angle UTS$

Explanation of Solution

Given information: U is reflection of S in the line k

U is the reflection of S in the line k and T is on the line k. Here, $\overline{ST}$ is the image of $\overline{UT}$ and vice versa. Hence, image of $\angle STU$ will be $\angle UTS$ .

Therefore,

The reflection of $\angle STU$ in the line k will be $\angle UTS$ .
