Question

Use the ankle shown to determine if the lines are parallel

Answer 1

The parallel property is:

The above relation show the parallel line

so check for the given line:

Use straight line property then:

`\begin{gathered} q+105=180 \\ q=180-105 \\ q=75 \end{gathered}`
`\begin{gathered} q+r=180 \\ 75+r=180 \\ r=105 \end{gathered}`
`\begin{gathered} p+105=180 \\ p=180-105 \\ p=75 \end{gathered}`

Similarly:

`\begin{gathered} s=75 \\ t=105 \\ u=75 \end{gathered}`

So given lines is:

So give lines are parallel to each other.
