Parallel and Perpendicular Lines

Parallel and Perpendicular Lines. Parallel Lines. Two lines with the same slope are said to be parallel lines. If you graph them they will never intersect. We can decide algebraically if two lines are parallel by finding the slope of each line and seeing if the slopes are equal to each other.

Lesson 2-3

Pairs of Lines. Lesson 2-3. Parallel Lines. Parallel lines are coplanar lines that do not intersect. Arrows are used to indicate lines are parallel. The symbol used for parallel lines is ||. In the above figure, the arrows show that line AB is parallel to line CD.
