Question

The terminal whether a b and AC

Answer 1

`AB\perp BC`

Step-by-step explanation: For two lines to be parallel , the angle connecting them has to be 180 Degrees likewise for the perpendicular case the angle connecting the line should be 90 degrees, Mathematically, this means:

`\begin{gathered} \angle\text{ABC}=180^(\circ)\Rightarrow\text{ Parallel Case} \\ \angle\text{ABC}=90^(\circ)\Rightarrow\text{ Perpendicular case} \\ \end{gathered}`

In this case, the angle between AB and BC is as follows:

`\begin{gathered} \angle ABC=90^(\circ) \\ \end{gathered}`

Therefore the answer is:

`\begin{gathered} \text{ }AB\text{ and BC }\Rightarrow\text{ Perpendicular} \\ AB\perp BC \end{gathered}`
