Lines Continued

The other day I asked questions about lines. These are a few more questions.

• How do you know when lines are parallel?


• How do you know when lines are perpendicular?


• How do you write an equation of a line perpendicular to a point?


• How do you write an equation of a perpendicular bisector to a segment?

PreCalc and Calc students

There is a term in mathematics called the "normal line". See if you can find out what it means.

Have a great day.
