Some facts
- Two lines k and l are parallel if they have identical line scope:
where:
- a - line scope, the same for both straight lines,
- b1 - free coefficient of the first straight line,
- b2 - free coefficient of the second straight line.
- a - line scope, the same for both straight lines,
- Two lines k and l are perpendicular if line scope of the first is negative inverse of the second one:
where:
- a - scope of the first line,
- b1 - free coefficient of the first straight line,
- b2 - free coefficient of the second straight line.
- a - scope of the first line,
- If lines are parallel, then they have no common point. Colloquially, one never crosses another one.
- If lines are not parallel, then they intersect exactly once in the point with below coordinates:
where:
- a1 - scope of the first line,
- a2 - scope of the second line,
- b1 - free coefficient of the first straight line,
- b2 - free coefficient of the second straight line.
- a1 - scope of the first line,
- To calculate the measure of angle created between straight lines we can use the following formula:
where:
- - angle measure between lines,
- - scope of the first line,
- - scope of the second line.
- - angle measure between lines,
