Parallel Lines

graph showing parallel lines

Parallel lines have the same slope.

Mathematically, we say if one line has slope m₁ and another line has slope m₂ then the lines are parallel if

m₁ = m₂

Interactive Graph

You can explore the concept of parallel lines in the following JSXGraph (it's not a fixed image).

Drag either point `A` or point `B` to explore slopes of parallel lines.

You can move the graph up-down, left-right if you hold down the "Shift" key and then drag the graph.

If you get lost, you can always refresh the page.
