About This Presentation

How do you calculate the distance between 2 lines in 3 dimensional geometry?
Watch this presentation to find out how to calculate the shortest distance between 2 parallel and non parallel lines. We also learn about skew lines and how to test if 2 lines are skew.
This is a useful topic for students o...

Here, we learn how to calculate the shortest distance between 2 lines What are skew lines? What is the shortest distance between 2 parallel lines ?

Yes, you can excel i n Mathematics ? Watch this presentation !

Shortest distance between 2 lines   +    

Q 1 Find the shortest distance between = ( and +6  

     

   

Distance between 2 parallel lines and     Skew lines are 2 lines that do not intersect and are non parallel

You can if you think you can !

Q 2 Find the shortest distance between the lines and =  

  The 2 lines are parallel    

Practice consistently !

Two non parallel lines    

Q 3 Prove that the lines 2x = y = -z and x-1 = -y-2 = -2z +1 are skew

  Direction ratios of the 2 lines are <1,2,-2> and <2, -2, -1>

  The lines are skew

What did we learn? How to calculate the shortest distance between 2 parallel and non parallel lines How to check if 2 lines are skew
