## How to Find Slopes of Perpendicular & Parallel Lines?

The slope of a line measures how steeply the line goes up or down. The larger the slope, the more rapid the increase. Parallel lines are found in the same plane but will never intersect. Perpendicu...

## Ways to Make Parallel Lines & Perpendicular Lines?

According to Euclid, a straight line goes on forever. When there is more than one line in a plane, the situation becomes more interesting. If two lines never intersect, the lines are parallel. If t...
