Parallel lines are defined as lines that lie in the same plane and never intersect, no matter how far they are extended. A key characteristic of parallel lines is that they have the same slope.

Parallel lines are defined as lines that lie in the same plane and never intersect, no matter how far they are extended. The key characteristic that ensures this non-intersection is that parallel ...

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 ...

Susanna Post explains a strategy for remembering the difference between parallel and perpendicular lines. In addition, she demonstrates the meanings of parallel and perpendicular lines by showing real ...

Two lines have equations \(y = {m_1}x + 3\) and \(y = {m_2}x - 7\). If the lines are parallel then \({m_1} = {m_2}\) and if \({m_1} = {m_2}\) then the lines are parallel. The gradient of a line which ...

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 ...
