Chapter 2.8, Problem 14PSB

To determine

In the graph plotted, interpret which rays are opposite

Explanation of Solution

Given information :

Four points

  $\text{A=}\left(3,-4\right),\text{B=}\left(0,5\right)\text{, C=}\left(0,-5\right),\text{D=}\left(-3,\text{ 4}\right)\text{ and O=}\left(0,0\right)$

are given to plot.

Graph :

  

Interpretation :

Opposite rays are

  $\begin{array}{l}\text{a}\text{.}\overline{\text{ OC}}\text{, }\overline{\text{OB}}\\ \text{b}\text{.}\overline{\text{ OA}}\text{, }\overline{\text{OD}}\\ \text{c}\text{.}\overline{\text{ BC}}\text{, }\overline{\text{CB}}\end{array}$
