Why not see how much you know about this topic already? Then work through the page and see if you can beat your score. Parallel lines are the same distance apart from each other all the way along ...

If lines are perpendicular to each other then \({m_1} \times {m_2} = - 1\) conversely if \({m_1} \times {m_2} = - 1\) then the lines are perpendicular to each other.

Mathematicians, it's a rainy day but Susanna Post, the 2021 Arkansas Teacher of the Year, is on the hunt. Can you help in her scavenger hunt to find examples of parallel and perpendicular lines? Rise ...
